In November, flat-Earther "Mad" Mike Hughes announced plans to launch himself 1,800 feet (550 m) above the Mojave Desert in a steam-powered rocket he made out of salvaged parts. His plan was to attempt to photograph the lack of curvature of the horizon to "prove" the Earth's flatness. The curvature of the horizon is subtle enough as to not be visible until at least 35,000 feet, so it's unclear exactly what Hughes hoped to prove. Nevertheless, his homemade rocket cost a reported $20,000, making it quite a deal compared with B.o.B's estimated $1 million rocket-launch scheme.
Unfortunately for Hughes, his launch was to take place on public land, and the Bureau of Land Management shut him down at the last minute.
Good work brainlet, next time though Google search the most basic information on the topic you're posting on so you don't look like a total fool.
"'Mad' Mike Hughes, the rocket man who believes the Earth is flat, propelled himself about 570 metres into the air Saturday before a hard landing in the Mojave Desert. He told The Associated Press that outside of an aching back he's fine after the launch near Amboy, California." -- https://www.cbc.ca/news/world/rocket-scientist-mad-mike-hughes-blasts-off-california-1.4592170Bonus:
