I thought an airplane PFD was a parachute? :->
Try to remember that when the wind changes and you end up in the water under your canopy and are loaded with your body weight in gear. As the parachute is dragging you under think back to this post. BTW,
if you can get out from under the canopy and away from the shroud lines, loose all the gear except that the gear that goes bang. Loose too much gear and the paperwork is annoying. Don't loose enough, and you get to meet the divers. Well not meet, but they get to "meet" you.
