From in the tower, you just type in the text radio ".join handle" where handle is the name of the player you wish to join. If you wanted to join my plane, you would type ".join Lephturn". I will then get a box that says "Alyster wishes to join you." with a button to either accept or decline. You will then be able to gun for me in a bomber for example. If I'm in a fighter, you will observer from my plane.
Beware, once you join somebody you can't get out until you are on the ground again. Once you are on the ground, you can type ".unjoin handle" to remove yourself from that player. If you want to get out before you are on the ground, you need to quit the program and restart it.
