Mine was Mid West Power 8(?).
LOC 429 SS on 4 AT metalstorms. I had a zipper on the rocket the year before, so when I patched it, I converted it to dual deploy. Worked great. Now back to MWP. Load the motors, wire the igniters, prep the altimeter, connect all the charges, load the rocket on the pad. Recheck igniters. Launch rocket. What was missing here? How about arm the altimeter!!!! Plus to add insult to already injured, only 1 or 2(on same side?) motors lit. Rocket exited stage left in a hurry. Wildman said the farmers found it next spring AFTER they had driven over it with the soil finisher. Not a scrap to be saved. Not even the shock cords!
Lesson learned; checklist for complex rockets!
