Re: Launch Day 7th October

It was a great morning of launching - 32 rockets in total.
Recoveries were all quite close, despite a little bit of breeze.

You're probably thinking of a system used in water rockets.

Re: Orion Launch Abort System (LAS) - (picture heavy).

Actually you probably want to avoid having 2 or more charges going off at the same time. You might want to cap the charge in with epoxy on 3 of them. Sealing the end of the motor sounds like a bad idea. The clay plug is designed to be a weak point; the clay nozzle - not so much. If you wanted to pl...

Is it really a shuttle? I noticed 2 sets of wings.

It's an Estes "Jetliner" kit - flies on A10-3 motors
