Video posted online shows the exact moment “Mad” Mike Hughes’ homemade rocket came crashing down to Earth after a failed launch attempt, killing the self-styled daredevil.

The video, posted to Twitter by Justin Chapman, a freelance journalist who witnessed and recorded the fatal crash, begins by showing the self-made rocket seconds before it takes off from a guide rail attached to a large white truck in Barstow, California.

Dust and sand fill the air as the rocket launches into the sky, and as the ship veers sharply to one side, a yellow and purple parachute can be seen falling off the vessel and floating down to Earth, surrounded by smoke from the rocket’s steam-powered engine.

The camera quickly pans down to the drifting parachute and then back up to the rocket — and follows the doomed craft until it crashes into the California desert while spectators who were watching the event scream.

The launch, which took place Saturday and was meant for a new Science Channel series called “Homemade Astronauts,” was supposed to have rocketed Hughes up to 5,000 feet in the air, the TV network said.

“Our thoughts and prayers go out to Mike Hughes’ family and friends during this difficult time. It was always his dream to do this launch, and Science Channel was there to chronicle his journey,” the TV network said in a statement.

Hughes, who believed the Earth is flat, had previously said his goal was to fly to the edge of outer space and see for himself if the world is round.

“I don’t want to take anyone else’s word for it,” he said after a March 2018 launch in the Mojave Desert in which he shot his homemade rocket over 1,800 feet into the sky, “I don’t know if the world is flat or round.”
