I have an idea that could simplify activation height calculations and make high speed moon landings safer. Right now the landertons seem to calculate activation height solely by current velocity. You don't need to change the current code, but you could use some simple equations to tell the user if they are going too fast. Something like v=sqrt[2GM(1/r -1/(r+ap))] G = grav const, M = mass of planet, r = radius of planet, ap = height of apoapsis. It will give you fairly accurate numbers for moons and underestimations for planets. No more landertrons turning red at the very last second
