Can you say "low Reynolds number?"

Curable by speed! *:-)

Clearly 'practical graphene' will require extensive, systemic thought (and
probably not a little new 'aereodynamic' research), but my nickel is on it
happening. After all, who can seriously imagine glider designers whining about
having a material so good it *hurts* their ability to improve performance
because it's too light?!?

My bet would be designers will use the immense strength to eliminate
Va, Vb and Vne speeds. A glider would reach terminal velocity first.
A higher turbulence penetration speed would facilitate higher inter-
thermal speeds. It would be especially beneficial for high altitude,
long distance XC wave flights. Imagine a 300 knot low pass.
