Up arrow key to go up. Down arrow key to go down. G for landing gear. Right arrow key to "drive" or "roll" right. Left arrow key to "drive" or "roll" left. Enter key to fire the gun. The gun was not made by me.

Shoot the red truck. Immediately after that, deploy landing gear. Hold left until you are going 25-45 m/s. Wait til the loading truck is in sight, then adjust controls accordingly so you can roll in.
