2001 - An unpiloted, solar-powered aircraft set two new world altitude records as it soared to 29.4 kilometres, US space officials said. The record for a propeller-driven aircraft was set when the wing-shaped plane dubbed Helios reached the altitude of 24.4 kilometres, beating the record set in 1998 by the aircraft Pathfinder Plus — a smaller version of Helios — said spokeswomen of Nasa’s Dryden Flight Research Centre. Forty minutes later, Helios broke another altitude record established by an SR-71 Blackbird reconnaissance jet in 1976 as it soared to 25.9 kilometres. Later, Helios reached 29.4 kilometres. The temperature at that altitude was -40 degrees Celsius. The flight was expected to last 14 to 16 hours, the National Aeronautics and Space Administration said.
