Taking off and landing a spaceship is extremely CPU intensive because of all the dynamic rooms it goes through, and it seriously breaks the game, especially landing. This is making people who have invested in space travel not want to engage in space travel for fear of overburdening the MOO. In light of this, landing a spacecraft should be refactored to cut out the extraneous rooms and instead just run a script that tests certain skills and determines a result without having to rapidly fall through hundreds of rooms to do so. Test piloting to make sure you don't crash and test aerotech to curb the damage the ship takes just going through the atmosphere, for example.
