I've got a much better idea. Why don't we let the engineers fly the aircraft; and the flight deck guys can maintain them.
On second thoughts, we'd better not - I can see it now:
Capt Engineer: "Whoops, this screw is loose! That's it, aircraft grounded!!"
Engineer Capt: "Missing engine? I'm sure that was on the MEL - fit to fly!"
To each his own... but I agree, a licenced engineer,
with type rating (and especially L1011/RB211 type rating)
should be paid more. Doesn't mean he will be, though!

Happiness is a warm L1011
