Fly any plane
Go to the mission builder, and create a mission. Click on "Add plane" if there is not already one on the runway. Then, right click on the plane icon. Change the aircraft type from the normal F-15E to any plane in the game (Su-27, MiG-29, 707, etc.) Note: The plane that is selected will still look like the F-15E on the inside. Press [F8] to switch to the outside view to see the aircraft. Additionally, the plane will still perform like the F-15E, allowing you to do barrel rolls and loops in a 707.
Go to make your own mission. Your aircraft should be listed. Delete what it says is you. From here, click "Add Aircraft". Select what you want to fly from the list. Select any other information and then click the "Computer Controlled" box to change it to "Human Controlled" if it already is not listed as such. Add what you want , save it, and fly it in the missions menu
Glitch: Flip and land
Go to "Training", then go to "Take off" and "Nav". When asked you to take off, set the throttle to 100%. Then, release the brakes and pull up. Do not stop pulling up. You will do a flip and appear to crash, but strangely just land. Note: Pull up as soon as you release the brakes.
