Thank You
Thanks everyone.
Thank you to all for replying - esp to those who pulled out the books! What you guys came up with is pretty much also all that I could come up with (hence it most likely is the correct answer!) You'd better believe that if I ever had to push that RAT switch I'd be holding it down for probably 2 seconds and 'willing' it to drop out! (I've been watching too much Star Wars). Thanks and hope I never have to touch that switch ... ever.
