Good luck with applying for WSOp, whatever you get its a great job...
Just remember that, assuming you get all the way through testing/training, you could end up on a number of platforms...
C130, VC10, Tristar, Merlin, Chinook, C17, Nimrod, KC135, E3 Sentry... Plus a few more...
Dont assume you're going to get what you want, be prepared for a varied job that allows you to transfer between different aircraft types, and completely different roles, all the way through your career!
