Well, if 26 minutes later qualifies as "about" 14 min later, then they have to widen the search area...No trouble was reported as the plane left radar contact, beyond Brazil's Fernando de Noronha archipelago, at 10:48 p.m. local time -snip- About 14 minutes later, at 11:14 p.m. local time
It is not the thunderstorms, its CB (cumulonimbus clouds) that tower that high. Actually, the top is the *least* dangerous area concerning lightning (NOTE: Not talking turbulence here, strictly *lightning strikes*), dont have the sources present on this machine but can provide if necessary.thunderstorms towered up to 50,000 feet (15,240 meters) in the area, so it was possible that the plane flew directly into the most charged part of the storm — the top of it.
Well, those "aviation expterts" are all the http://www.pprune.org/ members (yesterday it was visibly running in the bkgnd of CNN and they read from it literally w/o understanding what they read), so you get better info there (just have to learn to separate the troll inputs from the flywise guys inputs and to mesh through 20+pages).Although aviation experts stressed it was much too early to speculate about the causes of the crash, they noted that the accident was most likely caused by various factors that combined to cause a catastrophic chain of events.
It seems that they may never be able to recover the flight recorder -snip-
Why aren't these designed to eject from the tail when subject to a deceleration (like an airbag being activated in a car) and float, perhaps the data could then be communicated to a circulating aircraft by telemetry.
Well the possible impact area is so wide, and the sea is almost 4km deep. Even if found it they then have to raise it. Also:What information/data do you base this assumption/statement on, please?
Lost jet data 'may not be found'
French aviation officials have said they may never find the flight data recorders of an Air France jet that went missing over the Atlantic.
Because it would be deployed too often as you cannot standardize parameters...

Rattler, there are also concerns about the 'mountainous terrain' of the sea floor making it difficult, do you think this will be significant. They have a month to find it anyway.
-snip- Lightning occurs at much lower altitudes and the upper part of the cumulous clouds are far more stable. This is sort of what people mean by "flying over the weather." Most of the difficult weather is at lower altitutdes.
RattlerAn Air France Airbus A330-200 was destroyed when it crashed into the sea while on transatlantic flight from Rio de Janeiro-Galeao International Airport, RJ (GIG) to Paris-Charles de Gaulle Airport.
The airplane carried 12 crew members an 216 passengers. Flight AF447 departed at 19:03 local time (May 31) from Rio de Janeiro (GIG).
Last radio contact with the flight was at 01:33 UTC. The crew was in contact with the Atlantic Area Control Centre (CINDACTA III) when the flight reported over the INTOL waypoint, estimating TASIL at 02:20 UTC. INTOL is an RNAV waypoint located in the Atlantic Ocean, 565 km from Natal, Brazil. The TASIL waypoint is located 1228 kilometers from Natal. TASIL is at the border of the Recife FIR and Dakar Oceanic FIR.
At 01:48 UTC the aircraft went out of the radar coverage of CINDACTA III, Fernando de Noronha. Information indicated that the aircraft flew normally at FL350 and a speed of 453 kts.
A preliminary analysis of meteorological information shows that AF447 crossed through three key thunderstorm clusters: a small one around 01:51 UTC, a new rapidly growing one at about 01:59 UTC, and finally a large multicell convective system (MCS) around 02:05-02:16 UTC.
Over a time span of four minutes, starting at 02:10 UTC, a series of ACARS messages were sent -automatically- from the plane. The first message indicated the disconnection of the autopilot followed and the airplane went into 'alternate law' flight control mode. This happens when multiple failures of redundant systems occur.
From 02:11 to 02:13, multiple faults regarding ADIRU (Air Data and Inertial Reference Unit) and ISIS (Integrated Standby Intsruments System) were reported. Then on 02:13 the system reported failures of PRIM 1, the primary flight control computers that receive inputs from the ADIRU and SEC 1 (secondary flight control computers). The last message at 02:14 was a 'Cabin vertical speed' advisory.
On June 3, 06:40 UTC, a Brazilian Air Force R-99 plane positively identified four points of wreckage: Various objects scattered in a circular area of 5 km radius; an object 7m in lenght; ten objects (some of which metal) and an oil stain extending 20 km.
The Air France jet which went missing over the Atlantic sent 24 error messages minutes before it crashed
Weather experts said there was no evidence storms the plane encountered were "exceptional" for the season.
there was no guarantee the beacons were still attached to the flight recorders.
