one word: launch rails, wait that's two words, nvm.
Anyways, I was just trying to make a tiny drone but couldn't find a way to make it not explode on runway, so I built a launch vehicle that accelerates, then the drone detaches and the launch vehicle goes boom (even after I tried making it stop right after the drone detaches), If there was a platform that accelerates and then detaches whatever vehicle is on it... that would make my life a lot easier (Something like the zipline delivery drones launcher).
Please don't say I'm gonna have to do it myself.
