looking at whether it could have been caused by a typo. one possibility is that a trader may have put in a sell order for $16 billion instead of $16 million. that simple. whatever the reason, though, computerized selling kicked in, and the dow lost almost 1,000 points. it later recovered two-thirds of that loss. the big plunge caused sheer panic for some investors. before the markets gradually bounced back. money expert jennifer westhoven is here now to show you how it happened moment by moment. isn't it a scary, thought, jen. >> yes. >> just like possibly a human error, do, do, do, entered the wrong thing. >> that somebody could have typed the wrong zeros, a billion instead of a million that that may have happened so that could have been a very big deal. the dow already off $200 -- 200 points. here we go. i think it's going to come up. woof! this is the thing you don't want to see, total mayhem on the trading floor. there are pictures and sound of the people on the floor itself, that's the new york stock exchange but desks across the country, because what happens, robin, is, people have millions and millions of programs that are already just set up ready to go in case something like this happens, they want to protect our money so it sells. it doesn't know why or how. it doesn't know there's a mistake. it's trying to protect your money. so in minutes the dow off 9%, more than $1 trillion was lost on paper. >> what? >> in u.s. stocks. if you didn't sell, you didn't pay attention to this, right, nothing happened and things will probably right themselves but some people did, all because of the typo. the federal government looking into it, and of course, if it really was just a typo, then you expect things to kind of straighten out, and we are seeing the futures trading higher this morning. >> people who have a 401(k), if they were at work yesterday and they did not look into this, they did not see this happening and go oh, let me call someone, sell, sell, sell! >> right. >> is everything the same as it was before for you? >> mostly. >> no, right? >> mostly, yes. any stocks that you might own or something like that are fine but the thing is, what about your mutual fund manager? your mutual fund manager might have seen that and gone, sell! i can't let my people go bankrupt. i have teachers, cops and firefighters to look out for. glitch or not i can't let them go down the tubes. they might have sold to protect so you might end up with some losses. the nasdaq is voiding a lot of these trades. >> that would be nice because that stinks. >> yeah. >> and coming up, i want to talk about are there any stop gaps, in other words, that's really scary that someone could be sleepy and type something in and boom, my money's gone. parts of mashville's downtown are reopening after the horrible floods. you don't believe the mess left behind in some areas. the owner of this house was trapped inside surrounded by water when she saw smoke. luckily she and her dog were arrested by a man on a jet ski seconds before the house exploded into flames. ♪ so here you are now, nowhere to turn ♪ ♪ it's just the same old yesterday ♪ >> this is what i love about nashville. keith urban is one in a long list of country stars who helped the nashville tv station raise almost $2 million for the flood relief last night. president obama called brad paisley and asked him to spread the word fema is there and ready to help. nashville will recover, paisley told cnn's anderson cooper. >> you go through the neighborhoods and it's who are rick to see what we're seeing but amazing to see the volunteers that have come out. i've never seen anything like it. >> we've been driving around out here. i cannot believe the way that people just, they're showing up out of nowhere just to volunteer when they hear an area has been hit. that is what this town is all about. this is great people here. i've lived here since '93 and these are some of the most giving folks you could ever meet. >> to find out how you, too, can make a difference and help the people in tennessee g to our website, cnn.com/robin, hit "impact your world." some of the gran and go type lettuce mixes are being recalled. freshway row main lettuces has been connected to an e. coli night break. 19 people have gotten sick. the lettuce ended up in restaurants, store salad bars and delis. . see the list of states on our website at cnn.com/robin under "important websites." right now a four-story containment dome is closer to being fitted over the blown out well in the gulf of mexico. oil company bp says once it is in place it could trap as much as 85% of the oil gushing out and funnel it upward to a tanker. about 210,000 gallons of crude a day has been spilling into the gulf since that rig exploded last month. in less than ten minutes, correspondent richard lui will show you how that dome is supposed to work and what happens next if it does not work. here is a big story, football great lawrence taylor is in trouble with the law again. he was arrested in new york yesterday, charged with raping a 16-year-old girl. now jo carter has the details on how this supposedly all happened. good morning. >> good morning, robin. when you talk about football great lawrence taylor is arguably one of the greatest football players ever but has also had a lot of run-ins with the law. yesterday he was arrested at a holiday nin suburban new york. police say taylor had sex with an underaged prostitute, a 16-year-old girl, who had runaway from home in march. authorities say rasheed davis, a 36-year-old new york city man, brought the underaged girl to taylor's hotel room against her will. they say davis then beat the girl, and then handed her over to taylor, who sexually assaulted her. later the girl sent text messages to her uncle, who then went to police. taylor is charged with third-degree rape but he is a free man after posting $75,000 bail. taylor's attorney says his client did not have sex or rape anyone, and that he denies all charges. robin?

>> they're worried about that, too. we're using booms, obviously there's some concern about how well those boom also work. you can get an aerial view what have they're seeing on the ground, oil from before. the booms themselves, this is the concern. they're trying, of course, to continue to do those controlled burns on the surface. that's video from what happened yesterday. they're also deploying booms all over the gulf coast, we're talking about that earlier in the week, supposed to keep the oil from reaching land, that's the hope, but one boat captain here we've got for you, robin, is worried about high winds that can actually send it over the top of the booms, we're talking about the oil here. >> what i see from these booms anything above a 15-knot wind, it's over. i mean, it's not going to serve its purpose. >> the other problem is how deep the oil is in the water. this is the view from an underwater camera here, the booms are only a few feet deep so a lot of the oil could slip underneath them as well. >> that's what we're seeing there, right? >> that's right. >> richard, thank you. don't you hate it when you're standing alone at the atm and asking for your money, nobody's there helping you, and yet they say you're going to have to pay $2 or more to get your money out. ticks you off, doesn't it? lawmakers want to reel in those big fees. jennifer westhoven? it's about time. >> you know, you may hate like the bailout but it does mean there's a window maybe where people are more open to regulation so anyway, tell me what you think about this. i love this story because there's nothing i hate more than ending up maybe at an airport or something, and getting charged six bucks to take money out. you know it can happen, three bucks on each end. >> who is there helping you? >> exactly. they don't have to pay rent in the same way. it's a lot smaller for an atm than a bank. there's no teller, come on, it's a lot cheaper. how much does it cost the bank? one new york senator says it costs the bank 36 cents. you could be paying $2, $3, $4, $5, taken costs them 36 cents. senator shchumer would like to cap it at 50 cents. no comment from the banks but one atm threatens if that happens there would be fewer atms. in some ways i could see the atm maker getting a fee but my bank, what, they got an electronic transaction. how much can that cost you? >> i'm so over it, exactly, thank you. if would you like to give your opinion on that on facebook, go ahead, honey. it's okay if you don't agree with us. it's all right, it's about your views. cnn.com/robin. tiger woods is said to tee off in a couple of hours again. how is he doing after a terrible tournament last week?
