Hey guys, I am thinking on giving a seminar on Tilt-Rotor Aircrafts as
a part of my Mechanical Engineering Final Year Syllabus. However all
the info i found on the net (read Google) deals with the BA-609 and the
Osprey specifically and not with the concept of Tilt Rotors. Can anyone

That's right..... Your fired.
Pack up your bags and scram.

He said that Sikorskys have a "droop lock" in the cockpit that should
