As a refresher, here's the rocket on the ground:
Another shot to show you how big this rocket really was.
3... 2... 1... go!
Ejection charge fires and the drogue chute comes out. This chute is basically a chute that is intentially not big enough. That prevents the rocket from plunging back to earth at terminal velocity so that when the main chute fires, it doesn't just rip straight off. You don't want to fire the main at apogee though because then the rocket drifts for miles and miles and takes forever to recover.
This rocket was still a lot farther away than it looks, and hence a lot higher. I ran out of film on that roll before the main fired, but fire it did, and the rocket landed beautifully. A great flight.
