Now wait a minute, Eric, I think you might have slipped a decimal
point.

It's the "beanie" option offered by all the manufacturers to pilots that
like to fly with the hats that have the little button in the center. It
hurts like heck when turbulence throws you against the canopy, but it
doesn't crack the plastic!


More typical sailplane canopies, such as the HP-24 transparencies I've
been ordering, are made from 1/8" material; that's 0.125" or just over
3mm. Most of the broken European sailplane canopies I've seen seem to
be about 3mm thick.

All this time I've been flying gliders, and I've never measured one
until tonight. So, here it is: 0.096"! Lots thicker than I thought.
That's at the vent window opening on my ASH 26 E, the only convenient
point to put a caliper (I hope I never get the chance to measure it
elsewhere).
