"Mad" Mike Hughes, a flat-Earth conspiracy theorist, will have to wait a little longer to test his science-busting rocket.

Hughes had previously announced plans to launch himself in a homemade rocket to a height of 1,800 feet (550 meters) above California's Mojave Desert. But the launch, which Hughes had said would take place Nov. 25, did not happen. NPR reports that the Bureau of Land Management (BLM) "got wind" of the plan after the Associated Press reported Hughes' announcement. The agency shut down Hughes' launch, which would have taken place on public land.

The AP's original report stated that Hughes had built his steam-powered rocket out of salvaged parts in his garage, for a total personal cost of $20,000. Hughes also bought a motor home and converted it into a ramp. Once the rocket was aloft, Hughes planned to ditch it and parachute back to Earth.

This launch was supposed to be the first stage in a long-term effort to fly high enough to photograph the "disc Earth" and disprove that Earth is a sphere — a scientific reality that's been established for about 2,500 years and that anyone can prove for themselves. The curvature is subtly visible at about 35,000 feet (10,700 m) altitude if you have at least a 60-degree field of view.

Hughes claimed on YouTube that he had previously received tacit approval for the project from the BLM and the Federal Aviation Administration, and that the agencies reneged on their approval after news reports emerged.

He also said that his mobile launcher broke down in his driveway but that he had repaired it.
