I was told that Hawk turbines tolerate bubbles, they just loose a small amount of power should one be 'swallowed', they use significantly less fuel than most other turbines = less fuel per flight = less weight and do not require any form of UAT = less weight + less hassle.
Seems worthy of consideration to me.

Do the Hawks have screw on tailpipes? Looks like they are threaded at the end.
