This was pretty inspiring. I didn’t catch whether it had any guidance or whether it was just a dumb rocket. Note the epoxy camera cover melting as it approaches Mach Three. Things get pretty quiet after MECO at that altitude. Retrieving it a few miles from the launch site was pretty amazing. It must have had a pretty quick descent after climbing nearly 20 miles.
My junior high school rocket club never did anything nearly so cool, but I did once built a small, very sleek wood, plastic and paper rocket, powered by two “D” engines grafted together by turning them on the lathe to produce a tight socket & tenon joint, like a clarinet body– two “D” fuel charges stacked under a delay and ‘chute charge in the same case. It went out of sight and stayed there for quite a while- well over 1,000 feet– 1% of what those guys did. With the longest delay I could get in a locally available engine, it was still going so fast upon ‘chute deployment that it ripped most of the shroud lines. That was before I found out you could get “E” engines.
