IAN: I guess you didn't know about the witnesses.
There were over 150 witnesses of a streak of light.
Out of 102 that said where it originated, 96 said
it originated on from the surface of the Earth.
That's from the still covered-up (but leaked
through Aviation Week) NTSB witness report.
Dozens of witness accounts are available.
Those that I could place on a map are here:

Witnesses say that the streak left a column of
white smoke in its path. Solid-rocket fuel gives
off white smoke, yet burning jet fuel, what the govt
needs you to believe they saw, yields black smoke.
Of course when it comes to government claims, most
people seem are willing to believe black = white.

IAN: We agree, but...

IAN: That didn't happen to PAN AM 103, and it went
from horizontal to falling without any upward rise.
The forward velocity translates into a higher velocity
upon impact, but not a faster rate of fall. From the
physics textbook "Elementary Classical Physics":
"If one throws an object horizontally and
simultaneously drops a second body from
rest, the two objects strike a horizontal
plane at the same instant. The thrown object
strikes the surface with a larger velocity..."

IAN: It seems you also havn't seen the CIA video.

IAN: An object climbing upwards falls when it
has reached zero velocity. What evidence does
the physics-defying rocket-like rise fit? Have
you found a flaw in Ed Zehr's analysis which
proves that the noseless jet would stall in
under 5 seconds? If not, based upon what do
you make your claim? I guess faith in Govt.
Edward Zehr's dynamic analysis:

Zehr's static analysis (scroll to A REALITY CHECK):
http://www.freerepublic.com/forum/a40058.htm
The fact is that the CIA video has been abandon
by 99% of missile-theory critics, since they
realize that Ed Zehr is right. It is still
accepted by the government and the media,
who do not have to defend their claims.

IAN: Aviation mechanics will tell you that jet-engine
operation depends upon the proper angle of attack of
the relative wind, thus, "when the engines pitch up
the compressors stall and the engine flames out
unless laminar airflow is restored rapidly."

IAN: That's only because a fuel cloud covers
more area before it explodes, distributing its
max 60 psi force over a large area than the 1000
or so psi of a centrally source stick of TNT.

IAN: Any evidence to support that claim?

IAN: You've switched from the problem of knowing
what DID happen from the critique the CIA scenario.
Knowing what would have happened and knowing what
the CIA said happened are two different things.
We can know what the CIA said happened.
