How fast did they fly home? Also, how thick is the skin on a combat
aircraft compared to a civilian airliner?

I'll buy that the aircraft could stay together. The Mythbusters
simulation wasn't very comprehensive... But, then again, I know just
enough about high-speed aerodynamics to be afraid! :-)

you have other information?

You are correct, the Marshals are not using 9mm.

saying that the reason the perpetrators there
were able to shrug off multiple hits on their armor was because the cops
were using 9mm.

For those who don't like conversions, 9 mm = 0.3543307 inches. That is
pretty small. I never realized how small!

The thing those guys missed was the effect of cold temps on the windows.
They did it in the desert, where it was likely above 80F.
At altitude, the windows would be over 100 degrees colder. Plastic windows
become much more fragile at those temperatures.

Why do airliner cockpit windows have heaters?
The answer is to keep the windows warm enough and flexible enough so they
don't shatter if they hit a bird.
If Mythbusters had cooled that side window to -50C, it would have
disintegrated when the bullet hit it.

Why do they run them at altitudes that birds don't fly?

I assume your question is rhetorical, but the range of altitudes at
which birds may be found is far greater than most people suspect. I have
seen them 14,000 msl over the lower 48, and that is no record.

Other reasons: ice & snow, FOD (balloons and their payloads, kites,
model aircraft, wind- and vertical current-borne objects and material),
and of course the ever-present possibility of mid air collision -- all
of which must be considered at all altitudes within the operating envelope.

But these considerations have little to do with the advisability of
preventing skyjacking by any means necessary, including the use of
firearms by Federal Sky Marshals. As a cockpit crew member, a blown out
window is something I can deal with -- a medium sized problem: a team of
terrorists controlling the cabin is going to be a much bigger problem,
and it will have ramifications well beyond anything we are likely to
include in our discussions here.

As a side note on this, I'm pretty sure I once heard in a lecture or
presentation -- no!, it was in a wonderful quasi-documentary movie about
birds; was the title perhaps something like "Flight"? -- which described
one species of fairly small birds that migrate annually by taking off
from near or at sea level and flying over the Himalayas to a destination
far to the north, reaching altitudes higher than the top of Everest en
route -- and doing it nonstop.

Hope I don't have the details too far wrong here -- but if it stimulates
someone to dig out the movie itself, you may find it worth my possibly
erroneous memories.
