That means the aircraft suddenly experienced a nose-up torque of about 6,000,000 ft-lbs. Dividing the torque by the angular moment of inertia of 15,780,000 slug-ft sq gives and angular acceleration of .38 radians per second squared or 22 degrees per second squared. That means that in 1.5 seconds the aircraft pitched through 25 degrees and was completely stalled.

Ah, now we are into "theory." This guy's theory forgets that the tail surfaces are going to provide an aerodynamic force opposed to their being swung broadside into a 500 mph headwind. Where is his force calculation for that? Oops, I guess he forgot.

The whole thing is a "theory"....."my boy"....unless you want to go on record as stating that the NTSB-CIA cartoon was a FACT? Boeing doesn't think so. Neither does anyone else I've spoken to.

You also say, "as the aircraft traded altitude for speed."

Unfortunately, (for you) the radar data does not support this. There was NO trade off of altitude for airspeed. When the nose departed Fl800 stalled, and began it's decent. There is absolutely NO CREDIBLE EVIDENCE to support the NTSB claims.

Gee, if the guy's theory forgets that the tail surfaces are going to provide a resisting force against the nose-up torque, that is, by resisting being pushed down into the 500 mph headwind, then how is the plane going to suddenly climb unless the 3000 feet in altitude is gained over a much longer horizontal distance?

Except, when the explosion occured, the engines spewed out their turbine blades. The top of the horizontal stablizer had these blades embedded in its surface. The tail section of the aircraft broke off and could not have "levered" the fuselage. I believe the violent pitch up was the force that separated the tail. There was no sustained climb of several thousand feet. The location of the western most body verifed this finding since the body was of a passenger who was in one of the last rows and he was ejcted when the tail came off.

I've heard it described as, "all of the physical laws of the universe would need to be suspended for the aircraft to behave in the manner described by the NTSB.

Boeing has never agreed with the speculations of the NTSB.

[Dead Dog]

actually, he is right. The airplane is trimmed for a certain airspeed, with the cg shift aft, it will seek a much slower airspeed..i.e. pitch up (violently).

In short, the horizontal tail/elevator are now driving the pitch up, not trying to weather-vane.

It's simply an accelerated stall, and it is much more plausible than a 3000 ft zoom climb. Small airplanes will lose their engines occasionally, and they always pitch into a stall..nothing even close to a zoom climb. And this doesn't count the massive drag increased when you open up the front of a 747.
