A crackpot plumber and inventor has taken to the air in a hoverbike he built.
Colin Furze has unveiled his drone bicycle powered by a pair of two-stroke engines and rotor blades.
"It's the most outrageous thing I've ever ridden," he said.
"Feeling it lift for the first time was such a strange feeling. It only just lifts me off the ground.
"I tried out all sorts of frames; hacked bits off and added bits on, until eventually I started seeing results."
"The fact the hoverbike worked at all is a miracle, which proves you should try stuff even if you think you know the outcome."
