So, whatever happened to the Earth shattering KaBoom? After all, the Earth was blocking Marvin's view of the moon! :lol: Good stuff. Carl B.

Being in Utah, I assume he's working for Thiokol... Which would be Solid Rocket Boosters... And those are rocket motors, not rocket engines ;)

Meanwhile here's a little rocket motor eye candy... A nozzle for a 6" diameter rocket motor machined by yours truly. Phenolic carrier with a graphite insert. Throat is 2" diameter. This nozzle was used to lift a scale model of Marvin the Martian's rocket weighing 500 lbs to 500 feet. Good stuff!

He’s in California.

I built a liquid fueled engine for some Midshipmen a number of years ago. The injector wasn’t right as I recall. The oxygen and fuel mix wasn’t right. Didn’t generate enough thrust. Very cool project though. I’ll find a photo.
