… design your own space and air (!) craft or both? X-D

Kerbal Space Program is AMAZING hard core scientific space engineering simulation while being ludicrous creative and crazy.

A lot of navigation has to be „eyeballed“ (because on Kerbal (of course) computers were NOT invented yet X-D))

Look out for Kerbal 2 coming out in 2020 April? (src) on steam.

Hyper! Hyper! X-D
