It has been a long time since this happened so here it is again for the rotary skeptics.

"British explorer and mountaineer Edward "Bear" Grylls  has set a new altitude record by piloting a powered paraglider above Mount Everest  reaching 29,494ft (8,990m). He and his fellow pilot, Giles Cardozo, who had invented [not] and developed the parajet engine, set out on their attempt from the Himalayan  village of Pheriche (altitude 14,435ft (4,400m)) in the early morning of 14th May. "

"Grylls, 33, is a mountaineer, best selling author and television presenter who spent three years with the elite British Special Air Service  ("SAS") forces. During this time he was involved in a horrific parachuting accident in which he broke his back in three places, almost severing his spinal cord. Remarkably, in 1998, after months of rehabilitation, he became at 23, the youngest British climber to scale Mount Everest and return alive."

"Cardozo is considered to be one of the top paragliding pilots in the world, and it is reported that he and Grylls first came up with the idea for the attempt about a year ago when he had invented the engine that would take them up the mountain. "

"The answer to the problem was to design [not] and build a revolutionary 4-stroke rotary engine that was more compact and fifty percent lighter than a piston engine equivalent and almost twice the reliable power output for its cubic capacity. The basis of the Everest engine was a 294cc single rotor [AIXRO kart] engine producing 40hp as a standard normally aspirated engine. To make this standard engine block capable of delivering the required 100hp a huge amount of research and engineering work was carried out."
