He made the wings from zephyr cloth mounted on steel tubes, forming a large web under each arm which was clasped to his hips.

[5][6] Clem was badly injured during the opening ceremony of Gatwick Aerodrome, in London, England, when his primary parachute tangled in his wings.

He broke and mangled his shoulder on landing, after opening his emergency parachute at an altitude of only 60 metres (200 ft) and crashing into a taxi.

A crowd of 100,000 watched him frantically tug on the ripcord of his emergency chute, but that failed too, and Sohn, 26 years old, plunged to his death.

A UK manufacturer made the 'Welcom' Clem Sohn Bird-Man Glider, featuring "a red suited male figure with fold-out arms" and rubber wheels.
