I'll keep the airbag.. in the event of an impact hard enough to set it off, the glasses are likely to be the least of my worries
I'm left wondering why GA aircraft are designed with such cr*p access that you can't get in / out in a hurry. Don't fancy trying to exit a warrior in a hurry on the ground or in the air - AND the view out isn't that great either

A few 2 seaters (Robins spring to mind) have somewhat better access and a nice view.. but I'd certainly take a parachute if practical when doing aeros. keeps yer bum warm too..
On a humorous note, a servicable parachute is (IIRC) the only legal *requirement* to fly a glider in cloud in the UK. Reckon that's telling
