The first Solar Impulse airplane, HB-SIA, has demonstrated repeatedly that it can stay up all day and all night. The idea of perpetual flight has enticed designers for years, but the idea of a perpetual pilot has not – until the space age. Charles Lindbergh had a restless night before his May 20, 1927 takeoff for Europe and spent much of the 33-1/2 hour flight battling his nearly overwhelming need for sleep. A solar-powered flight will be considerably slower, and thus longer in duration, than Lindbergh’s epic voyage, however. With planned flights for HB-SIB, the second Solar Impulse craft, anticipated to span continents and oceans, the need for maintaining pilot health and alertness becomes imperative. As the team explains, “Over the several years Solar Impulse has proved that is its possible to fly with unlimited endurance. But as we know, Solar Impulse is more than a technical challenge. It is also about pushing human limits to new levels. “The Transatlantic …
HB-SIA Across America
This morning, Andre’ Borschberg and Bertand Piccard revealed the potential route for Solar Impulse’s Across America mission in a press conference at Moffett Airfield in Mountain View, California. The airplane is fully reassembled after being brought to America on a Boeing 747. Test flights will begin March 30th, and a technical flight “to test the aircraft’s mission readiness” for the coast-to-coast flight will take place March 30th. According to the Solar Impulse project, “The voyage will start in San Francisco on May 1st with stopovers in Phoenix (Arizona), Dallas (Texas), Atlanta (Georgia) or St. Louis (Missouri) on its way to Washington D.C. and New York City. The exact dates for each leg are undefined, as weather conditions play a factor in our flights.” The team promises, “Finally, we wanted to let you know that the Solar Impulse team is working very hard to open the hangar doors to all supporters and enthusiasts that wish to see the airplane. Working out …
Solar Impulse Shines in a Grand Finale
Nature’s vagaries threatened Solar Impulse’s planned flight all week at the 2011 Paris Air Show at Le Bourget Field, but the clouds parted company, the sun shone brilliantly, and the giant airplane delighted the huge crowd with its extremely slow pass down the main runway. Bertrand Piccard and André Borschberg, co-founders of the project, had accomplished what they set out to do – make believers in a clean, bright future of emissions-free flight. According to the project’s web site, “Gilles Fournier, President of Le Bourget airshow, declared afterwards: ‘This flight was the highlight of the air show. 30’000 people saw it this morning, and there was a very strong emotion amongst the crowd. This very intense moment reminded me of the prestigious history of Le Bourget air show. Solar Impulse is at the heart of this tradition.’” Almost 350,000 Air Show visitors and 3,000 members of the “international media” had an opportunity to view the 204-foot span machine in its …
