If you were a hippie in the 60s, you need to know. Its the dawning of the age of aquarius. Yeah, and Something Else thats cool. What . Osteoporosis is preventable. All osteos preventable . Right on if you dig your bones, protect them. All cbs cares mike morell is the former Deputy Director of the Central Intelligence agency. He is now a cbs news Senior Security contributor. Mike, everybody wants to know, and theyre all being cautious. What happened . So charlie, im being cautious too. I have not seen a single piece of data, single piece of evidence that would take us to a conclusion that terrorists brought down this aircraft. Thats certainly possible, but its also possible that it was some other factor like mechanical failure. Well just have to wait and see. But what if it was terrorism . What might it have been . So i think theres two possibilities, right . One is a bomb either placed on the aircraft somewhere in north africa where the plane had been earlier in the day, or a bomb placed on the plane in paris. Or it could have been an individual on the plane, even a pilot or copilot, who became radicalized and brought the plane down. I think those are the two terrorist possibilities. If it was a bomb that was placed on the plane in paris, what does that say about security in paris and concern about the threat of terrorism . That would be a very significant development. We know that isis has developed a significant, sophisticated Operational Capability in western europe, but this would punctuate that in a way that we have not seen before. And if in fact this is a new tactic, what does that say about terrorism in europe . It says that they can now bring it to the United States in a very significant way, right . By doing this exact same thing with a flight to the United States. Thats why this is so worrisome. Mike morell, thank you so much. The egypt air crash comes as the tsa is facing criticism for long lines at airports across the country. Transportation correspondent kris van cleave has more. Reporter growing flyer frustration made for tense moments at chicagos Midway Airport today. Thats why youre walking to the back of the line where you belong, right . Reporter but across town at ohare, passenger sarah king felt differently. It can be a bit tedious and bothersome, but i know its for our own safety and protection. Reporter with concerns the egypt air crash could be an act of terrorism, the Transportation Security Administration is caught between its need to thoroughly screen passengers and baggage and to get flyers through checkpoints in a timely manner, all while handling a surging number of flyers and a staffing shortage. Its a difficult balance between efficiency and Customer Service and security. Reporter tsa spokesman mark howell says the agency is monitoring the egypt air investigation. Theres a reason we do what we do. Okay . Why do you got to take your shoes off . Because weve had instances of the shoe bomber, okay . Liquids, the liquid restriction, is based in reallife incidents. So as things happen in the world and as threats evolve, the organization kind of has to evolve with it. Reporter following the metrojet bombings and the isis attacks in paris and brussels, the tsa has increased screenings of airport workers, checked luggage and cargo in addition to extra scrutiny of passengers and their carryons. In chicago today fbi director james comey. The lines are an enormous pain, but please know the lines reflect a commitment in this country to make air travel safe. Air travel in the United States as against the terrorist threat is far, far safer than it was 15 you accident years ago. Reporter so far the egypt air crash has not resulted in a visible increase in security at u. S. Airports. Charlie, tomorrow the tsa administrator, Peter Neffenger, will be here in chicago to discuss the agencys efforts to address the marathon lines impacting the area airports here. Thanks, chris.

A cbs News New York times poll shows Hillary Clintons lead over donald trump nationally has fallen from 10 points to 6, and trumps unfavorable ratings have fallen eight points to 55 . Trump is making good on a vow to make bill clinton an issue in the campaign. Heres nancy cordes. Reporter in an interview on fox donald trump leveled a harsh accusation about former president bill clintons past. Its about groping and fondling and touching against a womans will. And rape. And rape. And big settlements. Massive settlements. 850,000 to paula jones. And lots of other things. Reporter they were referring to a trio of women who say bill clinton made unwanted sexual advances in the 80s and 90s. Mr. Clinton denies it. Two of the cases were plagued by factual discrepancies. Still, the accusations linger and will be a focus of gop ads against Hillary Clinton. She politically attacked Sexual Harassment victims. Reporter in an interview today clinton would not respond to trumps allegations. If you pick a fight with, you know, a bully, you know, youre going to be pulled down to their level. Hi, guys. Reporter typically, spouses are considered off limits. But mr. Clinton is not a typical spouse. His wife has already outlined a major role for him if she wins. My husband, who im going to put in charge of revitalizing the economy because you know, he knows how to do it. Reporter hes also relatively more popular. A new cbs news poll pegs his Favorability Ratings at 45 , compared to her 31 . Plus the clintons have been pitching themselves as a package deal for decades. Voters often say to me, we got two for the price of one and they like it. Reporter the topic of rape is murky territory for trump, who was also once accused of rape by his exwife, ivana, a charge she later recanted. And there is no dispute, charlie, that both he and bill clinton had multiple consensual Extramarital Affairs which made for lurid tabloid fodder for years. This is a sad day for us here at cbs news. Our friend and colleague and good man morley safer died today. He was 84. Morley was one of the premier journalists of the past half century and a pillar of the leading Television News broadcast of all time, 60 minutes. Steve kroft now on the life and legacy of morley safer. Here we are, on board the good ship dandahelu bound from mali to furadu. Suppose you had a few dollars and you had to get from paris to istanbul. Then this is how you would go. First class on the orient express. Reporter from the dawn of his career toyotas twilight, marley safer was above all a writer. A brilliant writer. He stares down from the podium like some Benevolent Bird of prey, eyes staring past that great beak. Its all wonderfully choreographed, every gangly movement. Reporter he knew, as mark twain put it, the difference between the right word and the almost right word is the difference between lightning and the lightning bug. Tarkook asoria, a fit old man in his 94th year, is on his way to his mothers birthday party. Reporter he relished working behind the camera. In front of it right here. Reporter not so much. People might find it very odd come on. But i really dont like being on television. It is not natural to be talking to a piece of machinery. But the moneys very good. The predominant feeling among the europeans of Central Africa reporter for 60 remarkable years morley did speak his words into the machinery. First from the middle east in europe for canadian television, then for cbs news. As the role of american troops in vietnam changes reporter he first went to vietnam in 1965. Come this way. Reporter his report on marines burning the village of kam ne shocked america and enraged the pentagon. This is what the war in vietnam is all about. Reporter the president thought he might be a communist. Somebody explained to president johnson that i was a canadian, and he said, well, i knew there was something wrong with him. Im mike wallace. Im morley safer. Reporter he joined 60 minutes in 1970, doing his fair share of serious stories. But he soon began staking out his own territory. The offbeat. The humorous. And the absurd. I dont want that hand on at all. Heel. Come on, boy. People trek from every corner of england to this country lane in hartfordshire to watch her work her wonders on dogs. Morley. Reporter in 1979 he interviewed the muppets. Is your wife here . No, shes not. Great. The fortune teller reporter morley had a passion for art. He sketched. He painted. I was giving a definition of life and death. This is the eternal. Reporter and in 1993 he riled the art establishment with a piece suggesting some of the emperors of the modern art world wear no clothes. Its a white rectangle. Right. Hes a minimal artist, and i would say so. Reporter some of his best interviews were with famous women. Anna wintour of vogue magazine. Bitch. Perfectionist. Lets try bitch first. Reporter ruth madoff, wife of convicted ponzi schemer bernie madoff. You must have known. I trusted him. Reporter film legend katharine hepburn. Do you feel like a legend .

Listen here boys im telling you now reporter his reports over the years touched many millions of viewers, who saw through his eyes and felt through his words im a 60minute man reporter the beauties, the complexities, and the absurdities of the modern world. Ive led a charmed life as a reporter, as an individual. A lot of it is blood, weight, toil, and tears but a lot of it is pure unadulterated luck, and ive been a very lucky guy. Again, a sad day at cbs news. A very sad day. Our longtime colleague morley safer has passed away. He was 84. We leave you now with one of morleys favorite stories, discussing a profile he put together of a legendary comedian jackie gleason. Jackie gleason was a really great talk about larger than life character. And away we go a man of remarkable talent. Being a wiseenheimer, alice. And we know a wonderful comedy presence. Really was the master of an era of american comedy. Bang zoom. Take 23. And he loved to talk about how well he was treated by cbs. When youve got good ratings and youre one, two, or three in the ratings, there is nothing your little heart desires that they dont provide. And i explained that we were then, 60 minutes was the number 1 show and we were not kings of the world. And he said, youre no gleasons. He was a really professionallevel pool player. He wanted to play a game. Sure you havent got any money . Uh, no. No. Gleason broke, and i was up first. Im an okay pool player. Im certainly no gleason. Let me qualify that. Im really a lousy pool player. But i suddenly was hitting these brilliant shots. Gleason looked at me. Eyes narrowed. Ready to kill. And he thought hed been hustled with a live camera on him. Hey. Hey. Good night, mr. Gleason. That little snide remark will cost you. Of course at that point i just blew the shot. Whereupon he just cleaned the table. Did you like that one, pal . Please. In effect, ive got to tell you, i let him win because i was so scared of him. Great shot. You didnt touch a ball. Wish i could do that. Thats the overnight news for this friday. For some of you the news continues. For others check back with us a little later for the morning news and cbs this morning. From the Broadcast Center in new york city, im charlie rose. Announcer this is the cbs overnight news. And welcome to the overnight news. Im don dahler. Its getting down and dirty on the president ial campaign trail. And the Party Conventions are still two months away. Hillary clinton blasted donald trump saying he is unqualified to be president of the United States. Clinton says the job requires steadiness, strength, and smarts and in her view trump doesnt have it. The comments come as a new cbs News New York times poll shows trump closing the gap. Last month clinton was up by ten points. Now its only six. Major garrett has more. Reporter connecting the dots on Donald TrumpsDaily Campaign activities can be, well, kind of a challenge. Foreign policy tutoring with nixonera secretary of state Henry Kissinger. The list of conservatives trump might put on the Supreme Court. Followed by yet another social media sizzler about bill clintons sordid past. If Hillary Clinton for some reason wins, your country will never be the same. Reporter in an interview wednesday donald trump previewed a potential general election attack, rehashing accusations made against former president bill clinton. In one case its about exposure, and in another case its about groping and fondling and touching against a womans will. And rape. And rape. And big settlements. Reporter known for an attack dog trump is also trying to change the perception his policies are not conservative enough. I have a lot of people that are conservative that really like me, love everything i stand for. Reporter as part of that effort trump released the names of 11 Supreme Court candidates he said were in the mold of late conservative icon justice antonin scalia. I thought what i would do is put this forward and this would be the list that i would either choose from or pick people very close. Reporter one person on that list, texas Supreme Court justice don willet, has repeatedly mocked the presumptive nominee on twitter even floating the idea trump might be a liberal in disguise and would rip off his face and reveal a laughing ruth bader ginsburg. Earlier in the day trump met former secretary of state Henry Kissinger seeking Foreign Policy advice. But republicans like senator jeff flake arent convinced trumps policies will stay consistent. Its a good sign that hes sitting down with Foreign Policy experts. Now, whether that will stick and whether hell have the same position next week as he seems to be developing now, we just dont know. Reporter after much internal debate trump has picked the lawyer to oversee his running mate. A. B. Calderhouse jr. Famous and infams in gop circles for leading the effort that put sarah palin on john mccains ticket in 2008. It wasnt too long ago that it looked like the Gop Convention in july would be a rough and tumble affair as delegates tried to deny donald trump the nomination. Now it looks like the political fireworks may ignite at the Democratic Convention instead. Nancy cordes reports. Reporter sanders told cbs news he is furious that democratic officials would accuse him and his campaign of promoting violence. And now theyre backing off. Theyre worried about more protests, but they know that a protracted conflict with their candidate might encourage more unrest. That is a lie. That is an outrage. Reporter sanders says Party Leaders should be ashamed for claiming he encouraged supporters to disrupt the nevada party convention. Shame reporter because they were upset about the rules. I condemn all forms of violence and personal harassment. But i also condemn Democratic Leaders for suggesting in any way that that is what our campaign is about, that we are tinged with violence, that were going to take violence to the Democratic National committee. Reporter he got some backup from Vice President joe biden, who was asked about the incident during a trip to ohio. Thats not bernie. What bernies going to have to do if that happens again, hes going to have to be more aggressive in speaking out about it. Reporter sanders has gotten the same message from several senate colleagues. The crowd was out of control. Reporter including california senator barbara boxer, who got caught in the chaos. When you boo me, youre booing bernie sanders. Go ahead. You think hes done enough to make sure it doesnt happen again . I hope that behind the scenes he is telling everybody to be respectful. Reporter the nevada protests reminded some of the 1968 Democratic Convention, when vietnam war demonstrators erupted into the streets of chicago after the nomination of hubert humphrey. I dont want to go back to the 68 convention. Because i worry about what it does to the electorate as a whole. And he should too. Reporter some sanders supporters have already begun posting plans to occupy the Dnc Convention in july, something the party chair is eager to prevent. Everybody needs to take a step back and a deep breath. We have to make sure that we can do everything we can to maximize the likelihood of being unified. She initially called sanders reaction to nevada completely inadequate and she said he put fuel on the fire. But now she says she is ready to turn the page. Memorial day is right around the corner, and aaa is estimating 38 million americans will travel for the holiday. Nearly 90 will go by car. Most of the rest will be heading to the airport. And thats the rub. Security checkpoints are already so backed up, thousands of travelers are missing their flights each week. Kris van cleave has the story from chicagos midware international. Reporter neverending lines, thousands of missed flights and passengers forced to sleep on cots, all caused by delayed security lines at chicagos busiest airport. Lawmakers on capitol hill are now asking congress to intervene. People are missing their flights, and the airlines are losing a lot of money. This is an economic crisis as well as a passenger crisis that we believe the Congress Needs to step in and fix. Reporter on wednesday American Airlines agreed to spend 4 million on additional staffing to take some of the load off the tsa. There were also calls for Chicago Midway International airport and ohare International Airport to hire private screeners. I think privatizing would absolutely be a huge efficiency and ultimately would make traveling safer for passengers, easier for passengers. Reporter so how did this mess happen . It started with a surge of flyers and now a Record Number of travelers are expected this summer. An additional 95,500 a day compared to last year. But since 2011 the tsa has lost funding and shed thousands of screener jobs. The Officers Union says there are 5,000 fewer tsa officers now than 2013. Theyre losing people and not replacing them at the same time they have this huge spike in travel. Reporter after a series of terrorist attacks overseas and screeners failing 95 of tests during a 2015 Inspector General investigation, new tsa administrator Peter Neffenger ordered increased security at checkpoints. Since it was created that has been a problem for them. Speed versus security. And atrying to get that right balance. Reporter last Week Congress authorized tsa to use 34 million to pay overtime and hire nearly 800 additional screeners by mid june. Southwest airlines ceo gary kelly. I do believe that the administrator has a good plan but its just going to take a while to execute. Reporter all right. So this is the end of the line here at Midway Airport. Another factor in all of this is the tsa was banking on the success of tsa precheck. Thats expedited screening for prevetted travelers. They hoped that would offset some of the job cuts. However, signups for tsa precheck have lagged by the millions. Now, next week the tsa for more than half a century morley safer was a fixture here at cbs news. And now just one week after announcing his retirement morley has passed away. He died in his home in new york city. He was 84. Morley safer leaves behind a treasure trove of stories from every corner of the globe. Steve kroft took a look at his life and legacy for 60 minutes. This is morley safer reporting. This is morley safer. Reporter when he first spoke those words on television, Dwight Eisenhower was president. It all began when an officer reporter morley and Television News grew up together. The question remains, are the American People prepared to lose more and more young men in vietnam . The revolution, the original Chinese Revolution reporter across the continents and across the years he covered a huge range of stories. Last night reporter for some his slightly oldfashioned name took some getting used to. Okay. Whats his name . Morley safer. Right. Got it. My name is morley safer. Reporter but eventually im morley safer. Reporter it became a household name. Im morley safer. Im morley safer. Im morley safer. Morley safer . Yes. Himself. How are you . Very well. Hi, morley. Hi, morley. How are you . Reporter everybody wanted to meet morley. Well oh reporter almost everybody. In a sense what youre saying is that reporter in a business thats fast moving and sometimes cutthroat, he survived and prospered, either outworking, outfoxing, or outliving everyone else. And always did you murder those patients . No. Reporter trying to get to the bottom of things. What goes through your mind . Are these companies ashamed . What do they do down there . They really go after you. Admit, it youve got a temper. How did we get in this fix . Reporter like all of us hes got his contradictions. He swears in all seriousness that looking into the camera lens, as hes done for six decades, is not his thing. I really dont like being on television. I find it intimidating, discomf discomfiting. It makes me uneasy. It is not natural to be talking to a piece of machinery. But the moneys very good. [ phone ringing ] reporter contradiction number two. Though morley is impeccable in dress, manner, and thought, his office has always been a shambles. Visitors are shocked to see it. An avalanche of books on art, on history, old newspapers, old scripts, remembrances of stories past. The cleaning crews were often horrified. They found a piece of cake behind his desk from 20 years ago. And a couple of dead mice. Hello. Reporter jeff feger is the boston at 60 minutes. He and the rest of us spent many hours in that splendid mess listening to morley hold court. He loves being a reporter. Hes always loved being a reporter. You get that when youre around him. It rubs off on you. Reporter from the beginning morley went to Great Lengths literally to find an offbeat story. Here we are on board the good ship dandahelu bound from mali to furadu. Reporter there he is 37 years ago sailing the indian ocean to a tiny island called furadu having the time of his life. It is on rare days like this that you must ask, do they really pay me to do this . Yes. Reporter it turned out there wasnt much happening in furadu, but it really didnt matter. Are these dangerous waters here . Reporter the story was just getting there. Texas moon is shining and there he is three years ago out in the middle of nowhere again. A tiny town called martha in west texas. Cattle country. A place where cowboys live in peace and harmony with artists and hipsters. Its nutty. Its this cultural little hub in the middle of nowhere. We think its the best small town in america. Morleys stories were always an adventure. And sometimes in places people couldnt imagine going. Reporter in 1977 viewers traveled with him on the fabled orient express, paris to istanbul. He found out that somewhere along the way the trains romantic reputation had gone off the tracks. A train that once carried only firstclass passengers now is made up almost entirely of secondclass carriages carrying turkish Migrant Workers home. Hes such a natural. Hes so good at it. When you watch him youre just pulled in. Reporter morleys friend tom brokaw of nbc thinks theres a key element to his success. You have to be who you are. He did not take himself so seriously that he seems like some kind of a phony. When he was on television, he was morley safer. Right here. And his interest and his intellect and his humor i will cut off your mike, sir. Shut up shut up, safer. All came through. And people saw that. Reporter especially the humor. Morley likes to laugh. And america laughed with him. Heel. Reporter he profiled barbara woodhouse, the famous and slightly dotty british dog trainer. Left hand in front, mrs. Field. She had the voice why are you touching her back . Of an angry regimental sergeant major. Halt. Sit when i say halt. She would say its time for walkies. Walkies. Walkies. Reporter the dogs would just snap to attention. That was excellent. Is your wife here . No, shes not. Great. Reporter while interviewing the muppets he was hit on by that femme fatale, miss piggy. Morley. Yes. Could i see you later . Of course. Thank you. I must say shes a fascinating woman. She can be very, very aggressive. But very sexy at the same time. I thought 60 minutes was a highclass show. Reporter morley was at his best working with producer john tiffen, two politically incorrect guys who loved doing wild and crazy stories. In 1993 they went to a tango club in finland of all places wondering how did such a hotblooded dance wind up in such a coldblooded place . The finnish tango is not to be confused with the groingrinding passionate latin american version. The finns have managed to neutralize all that. Its a sad shuffle in a minor key. With lyrics to reaffirm a couples instinctive sense of hopelessness. Humors one of the hardest things to do on television. But in a subtle way morley accomplished it on a regular basis. Could it be the true secret of happiness is a swift kick in the pants. Reporter hes always had humor, authenticity and a sharp eye for the absurd. To the outsider thaez shows are another planet, part dazzling, part rocky horror show. Models who seem as angry as they are emaciated, wearing clothes fit for a cadaver. Reporter but morley insists theres one element above all thats crucial for television. The impact is what youre saying, not so much what theyre seeing. Reporter in other words, the writing. Up until fairly recently, he did it the oldfashioned way, on a royal instead of an apple. Turning out scripts that were rich in elegance and insight. He stares down from the podium like some Benevolent Bird of prey, eyes staring past that great beak. Reporter his writing is very much like music, whether hes profiling a man of music, conductor Michael Tilson thomas, or a man of the cloth. Timothy dolan is hard to miss. This bully, overweight, cherubic irishamerican charges through life like a holy bulldozer and always ready to refuel. Stick around. Get me a cold beer. Reporter or writing about a great name from history. In the french countryside he loved on the very edge of the wheat fields he painted so vividly, here lies vincent van gogh. He knows how to make every sentence count. Without being pretentious or showing off. Reporter historian David Mccullough is another typewriter man who knows a thing or two about writing. And hes a big fan of morleys. This is where she grew up. Southwest d. C. Guns were the music of the street. Drugs were the currency. And the violence was not operatic. His narration, his story gave to whatever the camera was showing a depth and a human value that it wouldnt have had if anybody else had been doing it. In your most idle moment are you hearing music .

Well, it didnt take long for marijuana sales to go from the Street Corner to highclass dispensaries, and now that its becoming more mainstream, pot is attracting a new generation of users. Seniors. Barry petersen has the story. Reporter these seniors are learning how to fill their prescriptions im using it for pain. For pain . Okay. Reporter at a pot shop. Its got triangle kush. Reporter in california, where medical marijuana is legal. Let me get two aiths of that. Reporter they want to know the highs and lows of marijuana use. Just three of those. Reporter for the aches and pains of growing old. Like with all medication, how to use it. Reporter 80yearold eva aguilera uses it to help with mobility. Every medication has a risk. Ive made my choice. Reporter seniors account for only 14 of the nations population, but they use more than 30 of all prescription drugs, including some highly addictive painkillers. So pot is fast becoming a pill alternative. Marijuana use is up 53 with the 55 and over crowd. I want the 500 milligram. 20. Reporter harborside in oakland is one of californias largest medical dispensaries. The first stop were going to make is here. Reporter owner Steve Deangelo wants more seniors to make the switch. Theres an ironic, almost tragic phenomenon, which is that seniors who are one of the groups who can most benefit from using cannabis are the single group that remains most opposed to changing cannabis laws. Reporter that opposition started when seniors were just juniors. Kids growing up with movies like reefer madness. Marijuana the burning weed with its roots in hell. Reporter and government antidrug campaigns. Just say no today. Reporter its still illegal under federal law but now almost half of americans live in a state where medical or recreational pot is legal. Over age 50 is the Biggest Group starting to use marijuana. Starting . Yeah, starting to use marijuana. Reporter leyland ruckel is in colorado, where two years ago pot went on sale for recreational use. Rucker has been using it since the 70s. Its been a really positive thing in my life. As a writer its the best way being stoned is a good way to work. Reporter minds like the times are changing. This year marijuana use is expected to appear on the ballot in at least a dozen states. Barry petersen, oakland, california. Weve been following the trek of two American Mountain climbers trying to reach the top of mt. Everest without the aid of oxygen. What makes them unique is theyve been posting their adventure online as it happens. Well, theyre making the final assault on the summit. Dana jacobson reports. Windy. Reporter when Adrian Ballinger and Cory Richards faced a brutal storm tent collapsing on itself. Reporter with winds approaching 50 miles per hour. We got out and dug it out. Reporter their bodies were already depleted from climbing to nearly 25,000 feet, where the air is thin. Your body is literally starved of oxygen. So everything that you do makes you out of breath. Weve made the decision now that with this kind of weather no seeming breaks, weve got to go down. Whoo we were battered the next morning. And what youre seeing in the photographs and sort of the snaps is just pure exhaustion. We just got our asses handed to us. Reporter ballinger has led over 100 climbing expeditions on five continents as the owner of alpineglow expeditions. While richards was named one of National Geographics adventurers of the year in 2012. Theyre both part of eddie bauers guide and athlete team. They break us to the edge, and finding where that edge is and then figuring out if we can still achieve the thats what i love about this. Here we go again. So the very next day we woke back up. The weather looked good. We felt okay. And we went and decided to tag as high as we possibly could on the mountain. Reporter in order to eventually claim without oxygen to the top of everest at more than 29,000 feet, the two men have to adjust to higher altitude slowly. They do this by climbing the mountain in stages with rests at lower elevations in between to let their bodies recover. Going climbing. Reporter just one day after the storm they pushed over 26,000 feet, an elevation known to many climbers by another name. The death zone. Dun, dun, dun exactly. As you go higher your body simply cant regenerate. And every minute spent above that altitude puts you without trying to be too dramatic here, puts you closer to death. Reporter they planned to make their final push after most of the other climbers on the mountain who are using extra oxygen, have summited, giving them a clear path to the top. Without oxygen we cant stop moving. If we stop moving well freeze. We need a day without a lot of other people on the route and we think were going to get that in about a weeks time. Fingers crossed. Captioning funded by cbs its friday, may 20th, 2016. This is the cbs morning news. More than 24 hours since it disappear period, and still no sign of egyptair flight 804.
