1) spawn a vehicle. drive forward a bit. 2) Spawn a new vehicle. Same Spot. set span to 180. 3) Destroy both, with anything. 4) Drive the first one that spawns forward. 5) Set the vehicle to instant spawn after moving vehicle 1 forward. 6) Wait for vehicle 2 to spawn. When it does, grab Vehicle 1, press Y. 7) Spawn anything, preferably something small. 8) When that item is picked up, the vehicle has no gravity, when it isn't it's normal. ________________________________________ Notes: . It can be done with flying vehicles, but it has no point. You can move around while spawning the vehicles for the 1st time, just be close to the same spot. A Chopper on Sandtrap is my favorite combination. Picking up the remaining vehicle will give you the linked item. I wrote this to add on to the main post, he missed some important things here. Yes, this glitch is old. [Who votes this is better than his post. XD]
Actually, you can go to the item menu and Press "X" on a highlighted item to get to the secondary respawn option menu. It's a handy tip for forging.
