Land on a beach (I've done that several times)
Fly under a bridge (not yet)
Fly an airship (not yet)
Fly a fast jet low level (god that was good)
Fly high enough to see the curvature of the earth (still working on that).
Thermal a glider for a couple of hours (very very relaxing, in a strangely demanding sort of way).
Get winched out of the sea under a helicopter (well, it's flying! I'm glad to say that the one time I did this was for training).
