Casper......we had that same situation too when on flying with a VGS.

The gliders flew at a max of about 1000ft, the parachutes we were wearing needed 1000ft to open propperly and slow you down to the extent you break your legs (and every other bone)....upon landing

Since's he has probbaly done his flight now, I'd just like to say, the "scary" things about air travel, are NOT crashing, to crash isn't really a big problem.....there are much worse things than that
