Comments: After an initial delay, all three lit nearly
simulatenously. The 18mm on the C6-3 was fastest off the pad, but
was quickly passed by the 24mm D12-3. With it's long burn, the 24mm
E9-4 just kept going and easily outdistanced all the others. The
E9-4 was corkscrewing during boost. This was it's maiden flight
so I don't know if it always does that. The corkscrewing makes an
Interesting sound, though. The D12-3 tumbled to its landing. The
C6-3 and E9-4 both gently aero-shelled down.
