I knew of an RN aircrewman who made that very move and the next time I met him he landed on our flat-top on the scrounge after making the impressive UK- Sierra Leone trip. (He left suitably loaded with victuals, you have to look after your buddies!)
A great chap who seemed to be throughly enjoying his time in the Chinook Fleet. (He was of course a Jungly Crewie after all). He may even be still in now.
Edited: I cant believe I am in agreement with the polyester decked stacker! I need to lie down!
