I think this is the right forum for this question, I've looked else where but have not found this answer.
Does Kerbal allow horizontal launches from different altitudes on earth ? or just launch pads ?
If not can I raise a launch pad to a 50,000 ft mountain side (though it would be stationary) ? I'm interested in the academic math and physics involved.
Specifically how big (mass) a rocket would need to be to put a 3 kg payload in LEO.
TY, Patrick
