@Delano1226 It’s optional, there is planes already in the game, or you can make your own plane. I’m pretty sure these planes are from mods in the video.
Engine Failure: Put a Minigun in the engine, then click play, click on Air-To-Air, a icon should appear, click it, the Minigun will activate and your engine will be on fire, NOTE: In some cases, this may be difficult to effectuate, If this doesn’t work, try placing the Minigun in various locations. Others: To detach some parts of your plane, you must put a detacher on the part that you want to detach
