So I know there is a bar on the right of the HUD from space to orbital cruise, which gets replaced by a bar for orbital cruise to dpp, then a bar for OC to surface. But how exactly does glide work? The pucker factor increases exponentially with every kilometer as I glide closer and closer to my doom. How do you know you aren't going to slam into the planet before glide completes? You know...besides just leveling off your ship for safety. Safety is for wimps.
