The Solar Impulse prototype, HB-SIA, will be making its first night flights within the next month, according to a June 15, 2010 press release from the project team. With eight successful flights to its credit, the airplane will attempt two critical missions according to the release: “the first night flight ever by a solar aircraft “the first ever complete cycle flight to validate the possibility of long-duration flights without any fuel” “’To fly day and night with a solar aircraft is a human and technological challenge that has never been met so far, and an essential stage of the project’, says André Borschberg, CEO and co-founder of Solar Impulse. ‘Demonstrating that we can fly a whole day and night will …

The press release and pictures tell a beautiful story.  The CAFE Foundation offers its congratulations to the Solar Impulse team. This morning (April 7, 2010) at 10:27, the Solar Impulse HB-SIA took off from Payerne (VD) airfield on its maiden flight. Under the eyes of thousands of spectators from all over Switzerland, Solar Impulse HB-SIA slowly climbed up to 1200 meters. The next 87 minutes Solar Impulse test pilot Markus Scherdel spent familiarizing himself with the prototype’s flight behaviour and performing the initial flight exercises before making the first landing on the Vaudois tarmac. The execution of these various manoeuvres (turns, simulating the approach phase) was designed to get a feel for the aircraft and verify its controllability. “This first flight was …

Two weeks ahead of the 106th anniversary of controlled powered flight by the Wright Brothers, the Solar Impulse, HB-SIA broke its earthly bounds and flew 350 meters (about a quarter mile) at a height of about one meter.  Because the airplane does not yet have its solar panels mounted, the flight was made on battery power. Graphic © Solar Impulse/EPFL Claudio Leonardi The project’s press release leaves no doubt as to the importance, and the thrill, of the flight. “The results of the ground tests conducted these last few weeks to verify numerous parameters (the prototype’s controllability, acceleration, braking paths and, engine power) had been overwhelming positive, thereby leading the team to give the go-ahead to Markus Scherdel, the test pilot, to take the …
