Water depth over 3,500 meters, a surface debris field five kilometers long and strong undersea currents.
FWIW I seriously doubt that the cause of this disaster was a lightning strike.
Seems like a rather innapropriate venue for a sporting event.
Mr. Arslanian revealed few new elements, confirming only that the plane's crew had sent a radio message reporting turbulence as it headed towards the equator and that the plane had later sent a series of automated messages over a three minute period reporting malfunctions. He did not specify what these were.
Agreed - not given the warnings they apparently had. And lightning, like empty fuel tanks, just don’t cause planes to crash.
Sorry to rip open a wound there, but I’m sure others were thinking it also.
C’mon
Planes fall out of the sky from cruising altitude on a regular basis - nothing to see here - move along.
I agree - modern planes deal with lightning easily. So, what are some other possibilities? (No distress call - no odd data sent in - no Maydays... nothing.) What's left?
Read the account of BOAC flight 911 over Mt Fuji.
Turbulence can rip any aircraft apart.
Lightening can damage modern aircraft as well, especially those designed around ESD sensitive microprocessors.
Posts over on airliners.net seemed to indicate that the three-or-four minute sequence of automated ACARS messages indicated some sort of electrical faults, followed by an autopilot disconnect, then ADIRU (air data inertial reference unit, I think) and standby instrument faults, then faults on the primary and one secondary flight computer, and finally an excessive cabin vertical speed warning that might indicate a depressurization. So whatever happened to AF447 wasn’t one massive failure like a Pan Am 103 or a TWA 800. Things failed over a span of at least four minutes, apparently in a cascade of increasing severity.
The thing that concerns me is that even if they do find the recorders, if there were electrical problems, it’s possible that they might not have all the data on them. When the Swissair MD-11 crashed off Nova Scotia in 1998, both recorders stopped fully six minutes before impact because they lost electrical power.

Would it be excessively paranoid to think that perhaps they might not want to release an official statement about what caused the crash? If, say, it was terrorism-related?
Well...turbulence is a possibility, as they were cruising in an area of fairly strong thunderstorms, although turbulence hasn’t been directly responsible for the destruction of a jetliner in a long time. Two Qantas A330s experienced recent problems with their air data computers, one of them had an “upset” (a momentary loss of control until the pilots could wrestle it back) as a result. An inflight fire is always a possibility like on Swissair 111 in 1998. And you can’t yet rule out the possibility of some sort of explosive device or sabotage.
All we know is that Air France got a sequence of automated messages from the airplane between 2:10 and 2:14 GMT that morning, listing an increasing series of things going wrong. Sometime after 2:14, the plane crashed, out of voice and radar contact with anybody.

If that is the case, they probably would have sent a distress signal.
None was sent.
You're right - sometimes they glide to uneventful landings on abandoned airfields.
Is that a legitimate gif of TWA800?
Thanks for the information. Looks like it’s a “wait and see” situation...
