A jet-powered wingpack
Another variation on which studies are being focused is the so-called wingpack, which consists of a strap-on rigid wing in carbon fibre.[5] It is a mix between a hang-glider and a wingsuit. The wingpack can reach a glide ratio of 6 and permits transportation of oxygen bottles and other material.[6]
On 31 July 2003, the Austrian Yves Rossy, jumping from 29,360 ft (9 km), successfully crossed the English Channel in 14 minutes using a wingpack, having covered over 35 km (21.8 mi).[7]
