A California man is planning to take a 500 mph flight in a homemade rocket to prove the Earth is flat.
Mike Hughes, a 61-year-old limousine driver, plans to launch himself 1,800 feet and fly one mile over the Mojave Desert in his rocket made from scrap metal, according to the Washington Post.

He said his ultimate goal is a launch miles above Earth where he hopes to photograph proof the Earth is flat. He has never tested this rocket.
"It'll shut the door on this ball Earth," Hughes said in a fundraising interview with a flat-Earth group for Saturday's flight.

In 2014, Hughes was injured when he flew a quarter of a mile in his first manned rocket. He was dragged from the remains of the rocket and had to use a walker for two weeks, he said.
Many believers envision the Earth is a flat disc ringed by sea ice, which naturally holds the oceans in, according to the Washington Post. What's beyond the sea ice, if anything, remains to be discovered.
