WTC Aircraft Impossible Speed - More Evidence P4T

[Shallel Octavia]

(PilotsFor911Truth.org) - Since our article on WTC Aircraft Speed Analysis was written, more evidence has been gathered to reflect the research provided by Pilots For 9/11 Truth and in the film "9/11: World Trade Center Attack". A more thorough understanding and explanation of why V speeds are established based on wind tunnel tests performed by the manufacturer is also available virtually making the need to gather documents from Boeing based on wind tunnel testing, moot. We already have their results of such tests in the form of the V Speeds they have established through wind tunnel testing required by definition as outlined in the Illustrated Guide To Aerodynamics and all other related text.

The Argument - Reported speeds/control for the reported aircraft claimed -
"impossible" 
"improbable",
"The Elephant In The Room" 

The Evidence

Data - 
NTSB


Boeing - Boeing spokeswoman Leslie Hazzard in this recording saying 500+ mph at 700 feet is impossible.

(Interviewer asks -) "So there's no way the aircraft could be going 500 mph at [700 ft] altitude then?"

Boeing Spokesperson - (Laughs) "Not a chance..."

Limits set by the
manufacturer based on flight/wind tunnel testing 

(IMG:http://i47.photobucket.com/albums/f178/myphotos1960/767_V-G_Diagram...) 

The above is for a 767, reduce the speeds by 10 knots for a 757.

The speeds are based on the weight ranges in the A1NM Type Certificate data sheet which also give an altitude range. 

VD = 420 KCAS to 17,854 ft/.91M above 23,000 ft, linear variation between these points.

The above diagram is good from sea level, up to almost 18,000 feet. Above that, the Vg diagram moves to the left. In other words, structural failure speeds are less in terms of Indicated at higher altitudes. Real pilots can see this as they climb. The Vmo indicator (Barber pole) actually moves to a lower airspeed once you climb above the crossover altitude. The reason for this is the aircraft is no longer limited by raw dynamic pressure, rather it is now becoming limited by the effects of Mach (both drag related, which is why EAS is calculated using Mach number and good to above Mach 2). A good explanation of this is shown here.

Precedent - 

EA990 - 

China Air 747SP 

TWA 727 

Simulator Reconstruction

Modified DC-8 



All suffered in flight structural failure, crash and/or lost control and needed 10's of thousand of feet to recover, well below Vmo+150.... or was modified to exceed it's manufacturer's set limits in the case of the DC-8.

Evidence for those who make excuse for the government story - 

Opinion
"Because the govt told me so"
Aircraft Forensic Evidence - N/A

For those who make excuses for the government story - 

Please let us know when you find one verified pilot (or precedent) willing to support your claims that a standard Boeing 767 can maintain control and stability at Vmo+150, Va+220 --and pull G's-- out of a 10,000+ foot dive, while rolling on G's cranking into a 38 degree bank, to hit a target with less than a 25' margin for error - for a pilot with less experience than one who couldn't control a 172 at 65 knots. Please let us also know when you have any type of evidence for your argument other than opinion or "Because the govt told me so...". 

Founded in August 2006, Pilots For 9/11 Truth is a growing organization of aviation professionals from around the globe. The organization has also analyzed Flight Data provided by the National Transportation Safety Board (NTSB) for the Pentagon Attack and the events in Shanksville, PA. The data does not support the government story. The NTSB/FBI refuse to comment. Pilots For 9/11 Truth do not offer theory or point blame at this point in time. However, there is a growing mountain of conflicting information and data in which government agencies and officials refuse to acknowledge. Pilots For 9/11 Truth Core member list continues to grow. The need for a new investigation has never been more apparent.
