It's a large mpg. The corkscrew happened at 1000 feet when the rocket
hit a wind shear. Showed up nicely on the telemetry. We were shooting
for 16,000 feet and Mach 1.4 according to the sims.
As to anvil launching ... there is a rocketry group that launches 16
pound bowling balls annually as a competition. A tad scary as these guys
have a rep for iffy recovery systems.
Just got in from 4 hours of forging. Draw and taper. and again and again
and again ...
I love it.
Bob
