At the NTSB press conference, they just stated that both engines appear to be intact and that there are no signs of engine failure, according to George Black, NTSB Boardmember.
Time to put on the tin foil hat, the engines could have been serviced with something other than jet engine oil, and still have taken off, The bearings on the free turbine are not sealed and a certain amount of oil loss is expected.
Frankly due to the operating temperature of most jet engines it is impossible to completely seal the bearings of the free turbine, so they are sealed.
There are oil resevoir that feed the engines oil and after every flight these resevoirs are serviced.
if they were filled with somethingbesides oil the oil pressure gauges would still read pressure simply because they only read pressure to begin with.
If for instance they had been serviced with water, the engine oil pressure senders would have still read pressure, and there would still be enough residual oil to allow take off.
but as the water replaced the oil it's effects on the freeturbine bearings would have caused them to seize,
since we are taking about Turbo fan engines instead of tubro jet engines, and tubro fan engines have a large rotational mass attached to the free turbine on the front of the engine, it is not unlikely that the failure of the free turbine would have caused the engines to shear from the wings due to a sudden stop or vibration caused by the failure of the bearings.
As for the tail assembly, it also is bolted on, and could have sheared it bolts due to the same vibration that caused the engines to shear of the wings.
For get the tin-foil approach.
anyone speaking up and taking credit for the act?
There was a guy "Ken" that called into WABC radio after docking his boat. He claimed that he was on Jamaica Bay and helped load some wreckage onto police boats. One of the things he mentioned specifically was the Blue letter A, which is painted on the rudder. The rest of the vertical stabilizer was in about three feet of water. He described it well.
At first I thought his story was suspect but it has held up given the wreckage pulled from the bay. A transcript of his call has been posted on a few of these threads.
Depends on a lot of things. Powerful vortices are generated by wingtips... the strength of these vortices depends upon the weight and design of the plane, weather conditions (gusty winds break the vortices up), proximity to the ground. Lots of things.
In the worst case, wake turbulence has caused planes to be damaged and even crash, but it would be very irregular for a widebody Airbus to be damaged by this... the previous largest turbulence victim was, I believe, a much smaller DC-9, and that was a freak accident.

The engines on most jet airliners turn at RPMs above 30,000. Add all the variables and check the record, yes air craft regularly do come apart in all aspects of flight under such extremes.
It's the media that spins this new math and -- believe it or not -- some Freepers actually start repeating it. "No evidence yet" actually means -- no evidence yet. It's SOP IMO for all investigations.
The results were very predictable and non-effective.
I have also been in wake-turbulence on approach, climb-out as well as cruise. It the very worst, the aircraft rolls slowly no greater than 1 or 2 degrees and yaws only slightly.
The airline industry will collapse if it's not safe.. Lying about terrorist not being involved will postpone the inevitable, but not for long. The lie will be uncovered by a democrat talking (they really do care about lying when it's a Republican doing the lying) or some terrorist will hit another plane, and claim both of them. It's a twofer. Then it all goes.
The people who tell Bush to lie for his country are the same types who told the older Bush to raise taxes to help the people. We know how kind they and the media were dealing with that broken promise.
Bush can't save the airlines if they can't safeguard the citizens who fly them. And he shouldn't. If the airlines can't keep citizens safe, others who can will replace them. It's still a market economy. Let the market work.
Yes the government could be lying about the cause. however I see no evidence to suggest that the government is lying about the cause.
