Hi Dick,

I was in a few of those myself with Chris Styles however I was
mostly in the background. Even my airplane made it in there -
  used as a flying camera platform.

I ran across a streaming video of one of your Sighting segments
while looking through some Washington Capital UFO sighting
websites last night. KRandle was in there as well.

I'll check out that site and see if I can find the Mantell
segment. The dreaded spin has been utilized by the movies for
years as a deadly condition into which an aircraft can get - and
for some aeroplanes it is deadly [in particular most large
aircraft] however when I received my civilian flight training,
we had to do spins here in Canada in order to get our tickets.
It's disconcerting at first but you can get used to them-as is
evidenced by many aerobatic displays at airshows.

The P-51/F-51 was/is a tough machine and could handle spins
quite well. But what is not publicized by the movies - probably
because it is not as dramatic looking as a spin - is the spiral
dive - a wide decending/banking turn - in cross section like the
coil spring in a car - which is deadly for three reasons.

The first is that when entered into, it is not easily picked up
by the novice pilot. Secondly because it causes the airplane to
lose altitude very quickly and third because it causes higher
wingloadings for the outside-and higher wing-than it does for
the inside lowered wing causing a twisting motion. It's for the
last reason that I figure the F-51 went into a spiral whereupon
the wing separated. That eliminated one fuel tank and the
ruptured fuel line cross feeds probably drained much of the
remaining fuel, starving the  engine and stopping it before it
impacted the ground as evidenced by the condition of the prop
after the crash.

The engine wasn't developing power when Mantells plane hit the
ground.

It would be interesting to see the crash report on Mantell's
aircraft. I suspect though that it would not be as thorough as
its present day counterpart. BTW-we were impressed with the
treatment of the Shag Harbour Incident though the special
effects were unimpressive. However they spent much of their
limited budget on the actual search of the bottom and the use of
hi-tech equipment to do so. But for the most part they stayed
factual with little embellishment.


Best,

Don
