Solar Impulse – Décembre 2009 – Travail en exclusivité sur l’aventure de l’avion solaire : “Solar Impulse”, le rêve fou du ” Saventurier ” Bertrand Piccard et du pilote André Borschberg

Dubendorf Airfield, 3 December 2009. At 13:11 , the Solar Impulse HB-SIA, the first airplane designed to fly day and night without fuel, left the ground for the first time.

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 prototype up to its take-off speed.

As the aircraft gently took up speed, the huge wing of the Solar Impulse gradually rose into the air under intense admiration of the project promoters, Bertrand Piccard and André Borschberg. After some 350 metres of flight at an altitude of one meter, the prototype graciously landed on the centre of the runway, triggering a frenzied applause from the team.

“On the one hand I find it terrific to see a dream come true. For over ten years now, I have dreamt of a solar aircraft capable of flying day and night without fuel – and promoting renewable energy. Today, our plane took off and was airborne for the very first time. This is an unbelievable and unforgettable moment! On the other hand, I remain humble in the face of the difficult journey still to be accomplished – it’s a long way between these initial tests and a circumnavigation of the world”, commented Bertrand Piccard, initiator and President of Solar Impulse.

“This is the culmination of 6 years of intense work by a very experienced team of professionals! This first “flea hop” successfully completes the first phase of Solar Impulse, confirming our technical choices. We are now ready to start the next phase – the actual flight tests”, said Andre Borschberg, co-founder and CEO of Solar Impulse.
