Blaze,
There used to be a static line parachute jump into water included in the ETPS course, so as to let the students experience another form of aviation! Sadly, financial considerations put an end to this some time ago.
On my course, we all assumed that it was compulsory so "psyched" ourselves up for it. We then were asked if we actually wanted to do it! Needless to say we all did. We jumped from the back ramp of a Chinook which was great - no slipstream to jump into. The most scary part was being picked up from the water by the Royal Marines in a "Rigid Raider" and driven around Lyme Bay at warp factor 10 hanging on for dear life! And then, rather than going to the pub for a beer, we had to get back into the Chinook to fly back to base. No justice.
To back up what Tarnished has said, flight testing for me is the best job in the world, although it is not going to suit everyone. I was sold on becoming a test pilot from very soon after I joined the RAF. I wish you luck.
