Speaking of stealth mode, I saw an episode of “Elementary” a couple days ago where Sherlock had a trebuchet in the house. Trebuchets first fascinated me over ten years ago. Building one was my first welding project. It looked like shit, but was functional and could toss a golf ball over 100 feet relatively consistently so accuracy could be adjusted.
For “stealth mode”, it could be mounted in the back of a pickup truck and used to toss a rock over a house and through another house’s window. LOL.
This Trebuchet Simulator does the math on lengths and weights to calculate throw distance of different objects.

This is really cool…although not a stealthy as a rock at night. LOL:
