But one person in attendance not on the speaker’s list is commercial pilot and aeronautical engineer, Nila Sagedevan.
. . . .
Sagadevan was quick to point out one of the main problems with the government story is the low trajectory of the airplane, flying at high speeds and roughly only 20 feet off the ground for a long distance, another impossibility defying the standard principles of aviation.
“The evidence indicates that the airplane was flying low before it reached the Pentagon lawn since several light poles were sheared off several hundred yards away form the building,” explained Sagadevan. “With that in mind, the plane was traveling at about 400 knots at about 20 feet off the ground for a long distance prior to hitting the Pentagon.
“This in itself is an impossibility since the airplane would have been kept from hitting the ground by a cushion of air termed 'ground effect.' No pilot in the world would have been able to control the plane while maintained that air speed at 20 feet off the ground for that long a distance. Again, it’s just impossible but here I will admit that an expert is needed in order to explain the standards of lift and drag associated with flying a large airliner.

Search Airmen Certificate Information
If yes then could you tell me his Street, City and Zip Code cause these are required field's for searching someone.
“I am not sure if anyone has been in the cockpit of one of one of these big jets, but I will tell you there isn’t much space. How in the world would one man pull out two big pilots in cramped quarters while, at the same time, maintaining control of the airliner. Again, it’s just not going to happen.
“First of all, the supposed pilot would have been overwhelmed just looking at the complexity of the cockpit controls,” said Sagadevan. “He would have had no idea what to do, but we are led to believe that he was able to turn the jet around, head back to Washington D.C. and then bank at high speeds and at a low altitude, hitting a target which would have looked as small as thimble from the air. Again, it’s impossible and you don’t really need an expert to make this final determination.”

Utter nonsense. It is quite apparent that it is he who hasn’t heard about ground effect: A Boeing 757 will enter ground effect at about 125 feet AGL (not “altitude”, by the way).
I’ve no idea as to the basis of this person “calculations”. I happen to have a degree in aeronautical engineering with a major in Aerodynamics—a subject about which this “expert” clearly knows very little.
Anything that keeps the high-pressure air beneath the wing from trying to displace the air layer above the wing will reduce drag. When the airplane is less than a wingspan above the ground, the ground will break up the vortices and keep them from curling around the wing -- and that’s part of what we call ground effect. When the vortex is prevented from curling around the wing, the induced drag from lift is reduced.
Aircraft obtain increased lift and therefore better efficiency by flying very close to the ground: on a fixed-wing monoplane, about half the distance from a wingtip to the fuselage.

it's entirely possible that if they weren't careful they WOULD deactivate the autopilot when removing the pilots bodies from the seats. However, it's actually quite simple to reactivate the system.
However, the hijackers’ attempts to haul the pilots’ bodies out of the cockpit would surely have caused some degree of physical impact with the control yokes, which would have immediately DISENGAGED the autopilot. Autopilot systems on fly-by-wire systems are designed to do that (757s and 767s are both f-b-w types).
