Nope. The engines found were consistent with those found on board a 757.

Physically impossible? Are you freaking kidding me?
Being a commercial pilot I can safely tell you that a plane can break the sound barrier when flying low. a passenger Jet that can fly at altitude at 400mph+ @ 40,000ft. can easily fly in the thicker air down lower.
Look up density altitude and do the calcs yourself. In all honesty that statement was the least defensible of all the "proof" I have seen re: 911. On that note I am done with you and wont bother to respond again. I have a rule, never argue with the unarmed.
The saying 'an aircraft can't do that' is thrown out the window by anyone who studies these accidents.

I have been studying aircraft accidents for decades and one thing you learn is to ditch the rule book, and the record book when dealing with accidents. The second and final decent of Egypt Air broke all the record books and stunned everyone with the speeds the craft obtained before it started to break up. The deliberate ploy of opposite ailerons and elevator positions used by the relief first officer, not only doomed the airplane but it caused it to accelerate to never before understood full throttle speeds. The airplane didn't invert and spin like most direct impact crashes and this led to unthoughtful decent speeds.
All Boeing and Airbus manufactured planes no longer allow one person to hold these settings and crash the airplane deliberately.

That is why any argument about what a plane could and could not do on 9/11 is ignored.
I disagree. EgyptAir Flight 990 is certainly not the record-breaker you claim it be. Indeed, the descent was fast, but exactly what happened and the exact speeds reached whilst the aircraft was still intact are widely debated.
The problem is the idea that momentum alone could account for 990's more than a mile and a half in gained altitude. This is utterly ludicrous to anyone who understands the laws of physics, much less anyone who has flown or seen a commercial jetliner like the 767 ... In fact, the radar data was so at odds with common sense that it's accuracy was initially disputed by various aviation experts.

You know, So many theories abound about whether there was a plane or not, or what happened to the plane when it hit the building, where did the debris go, how did the plane disapear into the building. Etc.Etc..
I was thinking, alot of this could be cleared up pretty quickly with a test?
Boeing does all kinds of tests on there planes, smashing them into things etc.. For safety etc..
I wonder if they ever, or anyone has thought to smash a plane into a steel building like the WTC?
If anything it should be done to test buildings and planes incase these things happen again in the future.
If we were able to see that and know what would happen it would clear the air on a lot of these theories methinks!
Mythbusters...

Yes, it is widely debated. People here think all you need to do is search google for the Holy Grail about anything that happens in the world-including airplane accidents. Just does not work that way. In the case of EgyptAir the Egyptian government vehemently disagreed with the conclusion of suicide by the relief first Officer. There own investigation claimed the ailerons and elevator positions were due to faulty maintenance. Their report insist the decent plunge after the recovery to 16,000 speeds reached and exceeded mach 86 and faster due to the poor maintenance preformed on the hydraulics that control the ailerons and elevator movements. The opposite settings caused the unheard of decent speeds.
The conclusion of the NTSB report points out the Egyptian government's findings however the report doesn't disagree with them-just points them out.

The Egyptian government is correct-in the NTSB explanation the RFO shutdown the engines right after the autopilot was disengaged. If that is true then how did the airplane pull out of the dive and regain altitude. The weightlessness condition in the cockpit prevented movement by either the pilot or the RFO due to the g force from the first dive.
There is no answer for this and it's doubtful there ever will be-science can't explain it.
By the way the Egyptian Air Ministry complete report, with scientific data supporting their conclusion, is not on the internet-you have to buy it.
If you have studied the Medical Examiners report based on the autopsy results of the coroner in the case of TWA Flight 800 you would understand why there is no impossible in terms of aircraft accidents. It will haunt me for the rest of my life.

The primary radar data indicated that the airplane climbed for about 40 seconds after the FDR stopped recording before it rapidly descended again and impacted the ocean. Therefore, the relief first officer and captain had about 83 and 69 seconds, respectively, from the time the airplane began its initial nose-down pitch until it began its second (final) descent,
recognizes that the simulations could not duplicate the near 0 G loads recorded by the FDR during the accident sequence and that these levels prohibited both crew members from revaluing and reducing the elevators position.
