Helios To Attempt Record Altitude Flight SpaceDaily

A new world’s altitude record for a non-rocket-powered aircraft could be achieved over Hawaii this weekend by the NASA-sponsored Helios Prototype solar-electric flying wing. Engineers estimate the aircraft could reach at least 95,000 feet on this mission with 100,000 feet still a possibility, well above the current record of 85,068 feet for sustained horizontal flight set by a SR-71 in 1966.
