Land the Aircraft is a mini game located in Space Station Meer and VAB Building. The object of the game is to successfuly land your aircraft.
Start off by moving across to the opposite side of the building, where the runway is. Get the wheels out. Slow down, though release whenever the warning sign shows up. Once it's gone, slow down again until you've landed. Then hold the speed down button completely until it comes to a complete halt.
But be warned - Coming into contact with anything (including the floor if your wheels are not out) will force you to restart.
