On 4 November 2007, a new distance record was set for a micro-unmanned aerial vehicle (UAV) in Lancaster, California, USA. The “Pterosoar”, a joint project between Oklahoma State University and California State University (both USA), flew 120 km (74.5 miles) consuming only 16 of the 64 g of hydrogen carried on board in a pressurized hydrogen tank. Potentially the UAV could significantly increase this distance to nearly 500 km (310 miles) based on its fuel capacity.
