Brian Walker has created the world’s largest crossbow and codenamed it Project RUSH (Rapid Up Super High). This crossbow will boost a “rocket-propelled” craft 20 feet into the air. It’s currently awaiting FAA approval.
He plans to pull 10 gs as the carbon-fiber bowstring releases and sends his little spaceship-like vehicle soaring into the air while firing a jet turbine with 1350 pounds of thrust. He will be wearing a Russian space suit to help keep his innards in, and has hydrogen peroxide rockets to help slow his descent, but we can’t think his mother is very happy about this all the same
