Lidle, Langewiesche, and turns

On Anderson Cooper 360 about last night, (at least) one of their
sources pointed out that to make the tight turn to compelte the u-turn
at that altitude and turning left, a very steep bank is needed, and
that this can cause a los of altitude -- and the radar returns indicate
that 200' was lost during the turn.

IIRC, William Langewiesche talks about this in his Atlantic article
(Dec '93, it seems),
and maybe in Stick and Rudder (Stick and Rudder: An Explanation of the
Art of Flying
by Wolfgang Langewiesche, William Langewiesche, ISBN: 0070362408 Pub.
Date: September 1990).

I don't have a copy in front of me (of either -- the Atlantic article
is not one of the non-subscription ones, unlike the EgyptAir article).


Does anyone have additional information? I know, the official version
won't be available for months, but there will gradually be information
available that will add to our picture. Which apartment was the engine
found in, btw -- the point of original contact?

A sidebar is that the pilot for the TV report siad, "this is very busy
space...I wouldn't fly solo here; having someone to do the radio knobs
[etc] would make a big difference" (I don't think that's verbatim, but
it should be close").

One way some good could come out of this, I hope, is if researchers
such as those at Purdue can use this as a check of their WTC models.
If properly calibrated, the models should show the difference in damage
(see http://www.sciencedaily.com/releases/2006/09/060911153219.htm,
and better copies of the simulation pictures at the Purdue site).
