Real Holder of the Glider Altitude Record, NOT RUTAN ON 21 JUNE

I vaguely recollect that altitude records require some fairly
healthy altitude gain to be valid in soaring. I believe this
applies to absolute altitude as well. IIRC one must
have a gain of diamond altitude to claim a absolute altitude
world record. I'm not certain about state records, but
may have read somewhere that silver gain is
required for state/national absolute altitude records...

AHA...Virginia requires:

3.0 Minimum Performance : Absolute Altitude records must include
an altitude gain of at least 3,281 feet.

Somebody else can look up the World Record requirement

The Burt Rutan SpaceShip One looks very light weight,
so I would assume it has some modest glide performance...albeit
likely at a higher speed than what we are used to.

Bet if it ran into mountain wave on the way back down
from space, it could climb in the wave. That would
meet the definition of glider then.

The SS1s drawback for a soaring performance is high Wing Loading and very
low aspec-ratio wings.
This means high stall speed and high sink rates, both non-conducive to
significant soaring performances.

The average sink rate according to their public data is 2500ft/min, and
stall speed with one person on board and no fuel was 70kts.

Already did, read my previous posting. It's 5000m, around 16000ft.

I'm betting Spaceship1 will climb at least 3281 feet after MECO.
