info....since, despite my time at ATS, I do not know how to 'parse' your post, and respond point by point, I use my memory to zero-in on one
aspect.
You have been lied to....and given false info.
EDIT...not sure really, where to begin...I'll start with the airplane. Firstly, and hate to make it a flying lesson...but how does an airplane
'turn'??
It 'banks' its wings. I could go into lift vectors, and all of the physics...but look it up for yourselves....it's readily available.
(edit) because, as stated above....your claim, "infoliberator" about the speeds of the airplanes. Again, more dis-info.
One has to understand not only aerodynamics, but also kinetic energy and potential energy to begin to understand.
A B767, at approx 1000 MSL (remember, the WTC Towers were about 1300+ feet tall) full throttle....will max out in speed....in fact, because of
compressibility issues at that altitude, and the increase in both induced drag and parasitic drag components....the maximum steady-state velocity will
reach a point....where the drag co-effecients will be enough to overcome the given thrust of the two engines.
BUT, this assumes a level, steady-state flight profile. WHAT is NOT taken into account, by these detractors, is the added use of Gravity.
If one wishes to dismiss this as a concept, then one would have to dismiss every instance of 'dive-bombing' as recorded in WWII history.
ANYONE who has ever flown an airplane knows the effects of diving...and the rapid speed increases that can result...as long as you survived to talk
about it afterwards.
AND....the pull-out to nearly level, as you bank to aim on target....I have pulled up to 6 Gs...(specifically in Aerobatic airplnaes, designed for
aerobatics. YOU each wear a parachute, per FAA regulations...) you do NOT 'black out' at 6 Gs. Far less G-forces were employed, on 9/11 ... based
on the final bank angle of UAL 175, prior to impact....I'd guess somewhere around about 2 Gs.
Just to compare...and, you can look this up, I am not pulling this out of thin air...an airplane in a sustained 60% bank, maintaining altitude and
speed, will 'pull' 2 Gs.
UAL175 was showing, at the end, about 35-40 degrees....final seconds.
WELL within the design parameters...EVEN IF there was a pull-up as well...
UNLESS and until everyone who believes false info learns how to fly, and actually understands not only the forces involved, but also the technical
information needed to truly understand the complexities....well...
In the meantime....here's an indication of how, even an 'amateur'....not even a licensed pilot, can actually fly a Boeing.....

*EDIT* to add, rather than pollute the thread....I've brought this up before, in other places....it bears repeating.
United Airlines has had a myriad of paint schemes...every time they change CEOs, they change paint schemes. UAL 175 had the 'business suit' design,
as I like to call it. (Please reference "airliners.net" for examples). The current CEO ordered that particular scheme...he left, went to
USAirways...and, funny, THEIR paint scheme suddenly resembled the old UAL scheme!!! (Again, go to airliners.net for reference).
So....let's at least debunk ONE aspect of the 'no-planer's' argument.
While I'm on about this, I can also debunk another point. The so-called 'pods' theory.
ANYONE who has seen a B767, overhead, with the gear up, will see the same 'bulges', right where the wings meet the fuselage. Those 'bulges' are
the landing gear doors, and associated fairings. So, let's put THAT BS to rest, shall we??
AND, don't take my word for it....look it up for yourselves!!!!
(hint)....Airliners.net, again....
