The Mk2 hornet,(the plane) is the main aircraft. But its different from most planes because it is powered by a missile, but it needs lots of height in order to start up. So, spawn at bandit airport,(or any other one of your choice) and throttle up the rocket. Fly to 40,000ft and then make a checpoint/spawnpoint there. After that go back into the plane editor and make the cockpit of the Mk2 hornet the main cockpit. !!WARNING!! YOU MAY DIE ALOT TRYING TO GET THE PLANE STARTED SO HAVE PATIENTS!!! Once the plane is spawned, let it fall for like 4-5 seconds and then activate group 1. Wait 3 to 4 seconds and activate group 2. Then fly for 45 seconds. The missile will run out of fuel and fall out of the plane and you can now glide freely. PEACE.
