This one involving the crash of the passenger jet egyptair 804. Tonight there are now reports there might have been smoke and a fire on board in the moments before that jet vanished from radar. The red eye flight from paris to cairo disappearing from radar about 175 miles off the coast of egypt. David kerley this evening on the signal sent moments before the jet went down. Reporter this jetliner apparently sent data before disappearing. Suggesting there was smoke, and possibly fire in the all important equipment compartment. The airbus a320 had a Data Transmission system know as acars which sent signals of smoke in the lavatory, and avionics smoke, which would be the equipment bay below the forward lavatory. A bay that contains the jets electronics which control the entire aircraft. This is a major clue to what happened. This is a major clue . I would personally say at this point, i will come off the bomb theory and say it was a mechanical failure caused by a fire. Reporter the messages obtained by the website aviation herald and not confirmed by abc were over a threeminute period before all the data stopped. Thats when the jet plunged into the sea at nearly 2 30 a. M. The pilots checked in with air traffic control, saying all was fine. But 16 minutes later at 37,000 feet, disaster.

Tonight weve learned flight 804 was piloted by captain mohammed shukair, his copilot mohamad assem. Both with extensive experience, and nothing in their public records that is suspicious. David kerley joins us tonight. We heard him say that he thinks fire is now the leading theory on what went wrong. And many are going to ask, was it a bomb or explosive device that started that fire .

Spotting debris on the water is one thing. But actually finding pieces of the fuselage can be more difficult because this part of the mediterranean could be 10,000 feet deep. The real prize for search teams deep beneath the surface, the black boxes emitting pings for only 28 more days. The race now on to find them. To get an accurate signal a search and rescue boat needs to be virtually on top of the wreckage, not more than a couple miles away. And tonight, so many Unanswered Questions for the families of the 66 souls on board. In cairo, this man, grieving four relatives lost.
