This would be the infamous “Plane Ride From Hell”, which was less of a legitimate fight than what happens when you let wrestlers have unfettered access to alcohol and fail to supervise them properly. Lesnar and Hennig were actually good friends, due to their common roots in Minnesota, but Hennig was a notorious prankster who enjoyed messing around, and during a flight back to America after a European tour, Hennig managed to goad his buddy Lesnar into showing off his amateur wrestling skills, resulting in the two of them rolling around the aisles, and according to at least one report, even slamming into the door of the plane. The fight capped off an incredibly tense flight full of multiple incidents involving drunken wrestlers, and resulted in WWE massively overhauling their conduct policies and adding extra supervision for future tours, as well as immediately firing Hennig, due to the entire thing largely being seen as his fault.
No, what happened is they told the hospital staff they found a dead body by the road. Then they ran away. After all, they were late for work. And speaking of late for work, the hospital treated Sandman's corpse by ramming an adrenaline needle into his heart. He popped back to life and called Tommy Dreamer to tell him he was coming to wrestle in his scheduled match. Tommy, of course, told him he was crazy and to get some rest.

One Third Of WrestleMania VI Competitors Dead Jim Hellwig Ultimate Warrior foreshadowed his death on 'Raw' just a day after WrestleMania XXX: "Every man's heart one day beats its final beat. His lungs breathe their final breath. And if what that man did in his life makes the blood pulse through the body of others and makes them believe deeper in something that's larger than life, then his essence, his spirit, will be immortalized by the storytellers -- by the loyalty, by the memory of those who honor him, and make the running the man did live forever."
