Having issues launching a space plane after launching its teleporting 1km up above the runway just for it to fall down and crash
opening the alt f12 console while loading gives the error (Ground contact! - error moving vessel up 996.814m)
mods installed are OPT and kOS on the latest version of KSP 1.4.1
