There should be a limited ammo gun on the bottom of the plane you can shoot with, and maybe a passenger seat. To take off you need to hold w for about 3 seconds, and to land you have to let the plane roll on its wheels for 2+ seconds, or else it explodes with the force of a c4, most likely killing the driver and other zombies. If you survive the crash via Flakvest, your mount will be dead for the rest of the round. The plane should be able to fly 10 seconds with full fuel, and fuel should regen fully in 15 seconds.
