The helo pilot's input on flying in such a huge mass of upgoing air would be
interesting.
Probably as boring as "less throttle" though.

Perhaps the most impressive thing about the Red Bull doco was the
helicopter camera rig. Staggering steadiness (at a price). Anyway,
back to Real Aircraft.
I wonder what is a real aircraft? A human carrying aircraft? Or any
glider?
It would be interesting to come up with some way of quantifying this.
Something involving the cost when new, the L/D, the lifespan, the
average flight time and distance covered. I guess Mike B can help with
this.
6-7 kgs weight, an LD of 8-9, a lifespan of say 5 years and a cost of
$5,000 (?) for a paraglider. Average flight time inland of 3 hours and
120 kms?
35 kgs, 15:1 L/D, lifespan of 12 years and cost of $12,000 for a hang
glider. Average flight time inland of 3 hours and 180 kms?
70+ kgs, 40:1 L/D, lifespan 30 years (?) and cost of $100,000 (?) for
an ultralight sailplane. Average flight time inland of 3 hours and 250
kms?
280 kgs, 50:1 L/D, lifespan 40 years (?) and cost of $180,000 + for a
conventional sailplane. Ditto.
350 kgs, 50:1 L/D, lifespan of ?? years and cost of $220,000+ for a
stink wing (SLG). Ditto.
Regrettably, I think the unreal aircraft would come out rather well.
