OK. I’m now officially dumber than a Kerbal.
I built a few simple Kerbal rockets and they fell over (no casualties). ;-) That’s normal on the first try—I’ll just have to rethink the design.
Next morning I woke up and had a revelation: Why were all the rocket components oriented horizontally? Why was it so hard to use the snap-mode to rotate boosters etc. vertically? And why did the game launch my rocket from a plain looking street and not a rocket launch pad…?
I was… working in the airplane hangar and not the rocket hangar, wasn’t I… X-)
