This is the Mohonasen Tarc team's ground test firing of Warrior 1's engine with the ejection charge.
The first rocket we launched had ended up lawn darting into the ground; which shows the reason for this test
The funny thing is the whole point of this test is just to see thelittle poof of gas at the end (after the initial flame) which ejects the bottom of the rocket away from the top opening the parachute.
