Excellent point Brent. That certainly is a potential risk, especially
with long bridals.  I admit that I don't do this often -- but it sure
is a great ride.

Actually, I'm relatively conservative in my canopy flying.  I don't recommend
doing much of anything besides preparing to land under 1000'.

I haven't ever done a down plane (I've done some CRW -- was in a 9-stack --
but I've elected to avoid CRW these days), but they do appear fun and safe
if done high enough off the deck.  However down-planes seem to be a favorite
low-bird stunt -- I wince when they bring 'em down till you can see the whites
in their eyes.  Anyway, do you (or anyone) know how much stress & pressure
down-planes put on a canopy?  Have you heard of anyone having canopy problems
while in a down-plane?  I haven't --  was just wondering ...
