a February 2012 episode of Top Gear (S18 E5) where he raced against a Skoda rally car driven by Toni Gardemeister with Richard Hammond as a passenger. The race started with the rally car launching down the rally course while Rossy and his support helicopter climbed to reach altitude, upon which he dropped and ignited his engines and followed the course to race the car. Periodical smoke dashes (such as those used by sky-writers or air force display teams) were used to track his progress. In the onboard footage of Rossy flying the tight and twisty course, one can see how he uses his body parts as control surfaces to perform various maneuvers. On 13 October 2015 a show flight was performed in Dubai. Two jet packs operated by Rossy and Vince Reffet flew in formation with an Airbus A380 jetliner. Troy Hartman: jet pack and parafoil In 2008 Troy Hartman started designing a wingless jet pack with two turbojet motors strapped to his back; later he added a parafoil as a wing. Fritz Unger: jet pack with rigid wings As of 2013 Fritz Unger in Germany is developing a jet pack called Skyflash with rigid wings about wingspan and two turbojets designed to run on diesel fuel. It is designed for takeoff from the ground using four undercarriage wheels on the front of his chest and abdomen. JetPack Aviation: wingless jet pack On 3 November 2015, Jetpack Aviation demonstrated the JB-9 in Upper New York Bay in front of the Statue of Liberty. The JB-9 carries of kerosene fuel that burns through two vectored thrust AMT Nike jet engines at a rate of per minute for up to ten minutes of flying time, depending on pilot weight. Weight of fuel is a consideration, but it is reported to start with per minute climb rate that doubles as the fuel burns off. While this model has been limited to , the prototype of the JB-10 is reported to fly at over . This is a true jet pack: a backpack that provides jet-powered flight. Most of the volume is the fuel tank, with twin turbine jet engines gimbal-mounted on each side. The control system is identical to the Bell Rocket Belt: tilting the handgrips vectors the thrust – left-right & forward-back – by moving the engines; twisting left hand moves two nozzle skirts for yaw; twisting the right hand counterclockwise
