Re-arm and Refuel - To re-arm and refuel, press Ctrl-R while playing.
Never Die - If your aircraft is heavily damaged and your sure it's not
going to make it, don't worry about it. Just exit the game NOT THE
MISSION. Then just go back into the game. When you exited it saved your
pilot. You won't get the points for the mission you were on, but it's
better than having a dead character.
