Rocketry in same era could be pretty dangerous.



But D sized engines on green plastic army trucks launched horizontally on the street, AWESOME.

For real excitement remove the clay and the 'ejection charge' from the top of the motor, replace with tightly packed black powder, seal it in with a bit of cardboard and wax...

Well we lost a payload out of one of our rockets today. Nose cone came off the payload section. We found the nose cone, but not the altimeter. Went back after dark to see if the leds were still lit, but i guess the 40 mah died long before we got back. Or it landed in one of the yards to the south of where we launch.
