One plus on reliability is a bleed air duct failure can distroy a

the squadron I was in due to a bleed air duct failure.

True, although I don't recall ever reading about a bleed duct failure
in a commercial airliner. I think it's very rare.


Not too rare, and it wouldn't lead to any real damage unless you were
very unlucky.. Anyhow, bleed is not used to powere gyros!
