Pilots for 9/11 truth explain why the high airspeeds (at low altitude) provided by the NTSB's analysis of the 767/757 flight profiles as flown in the 9/11 attacks on the WTC towers and the Pentagon are aerodynamically impossible and would contravene the laws of physics.
Also they allege that when several experienced passenger jet aircraft pilots tried on a simulator to emulate the flight paths of the alleged hijackers (who had no experience flying high speed jet aircraft) and fly the simulator into the buildings in the same manner as the hijackers allegedly flew real jet aircraft on 9/11 it was found to be practically impossible for them even as experienced pilots to hit the targeted buildings even after multiple attempts.
