Mythbusters and explosive decompression

They don't. They turn them on during descent because otherwise they would
still be cold enough to be fragile even after getting down into warmer air.



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

If Mythbusters had cooled that side window to -50C, it would have
disintegrated when the bullet hit it.

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"? --


"Winged Migration". Excellent movie, every pilot should see it. Twice.

My company's procedure for the 737 is to turn on the window heat a
minimum of ten minutes prior to takeoff and leave it on until parked at
the arrival gate. The window heat can be left all day long if desired.

Yes, but I am prohibited by TSA law from disclosing any more.

Few notes -

Some years ago I hit a red-tail hawk on the left windscreen of a 707
at 16,000 ft climbing out of Houston. Made a mess - no damage. If we
lost windshield heat, our limitation was 250 kts below 14,0000 ft.
Guess that bird didn't know he shouldn't fly that high.

Also some years ago, I saw a Gulfstream that belonged to a Middle
East head of state at a US repair facility with a bullet hole that
entered in the belly and went out the top. They flew it normally all
the way to the States The Gulfstream carries a higher pressure
differential than any airliner I know of with an 8,000 ft cabin at
51,000 ft. and usually cruises about M .82 on long flights.

Aircraft pressurization is controlled by how much air gets let out by
the outflow valve/s. With a small hole or two, the outflow valve/s
would automatically close a bit and the aircraft would pressurize
normally anyway. If you do a ground pressure check on any aircraft,
they leak all over the place anyway. In flight it would just whistle
a bit louder and that's all.

Forget the pressure vessel as far as I'm concerned. What about those
rather large wire bundles being fed by a couple of 120 KvA generators?
Ask Swiss air. How about the primary control system, hydraulic
systems, or 20,000 gal of fuel? Fuel; ask TWA/ American. What would
happen if that 9 mm went through the fly-by-wire boxes on a B-777 or
Airbus? Don't know that one yet, but I hope we never find out.

Myself, I'd be just as happy if they'd leave the cockpit door locked
and used the crash axe if necessary. Besides, I know some of those
guys that fly those things and there are a few I wouldn't want to see
with a gun!!!

Would you fly with them?

It proves nothing, Tom. I was merely concurring in Don's opinion. If you
need any further clarification, just ask.

Instead of an airpane?
