This achievement was made on the occasion of the Across America Mission which aimed at flying Solar Impulse from the West to the East coast of USA in 5 legs without using fuel.

The Mission was completed yesterday when André Borschberg (right in the picture) landed in New York John F. Kennedy International Airport after a 18h23 min flight from Washington Dulles. The landing happened 3 hours earlier than planned because of a rip in the fabric on the lower side of the left wing.

“This last leg was especially difficult due to the damage of the fabric on the left wing. It obliged the team to envisage all the possible scenarios, including bailing out over the Atlantic. But this type of problem is inherent to every experimental endeavour. In the end, this didn’t prevent us from succeeding in our Across America mission and provided an invaluable learning experience in preparation for the round-the-world tour in 2015,” said Borschberg shortly after landing,

André Borschberg was welcomed at New York by city authorities and also Bertrand Piccard (left in the picture), co-founder with Borschberg of the Solar Impulse project.

“Flying coast-to-coast has always been a mythical milestone full of challenges for aviation pioneers. During this journey, we had to find solutions for a lot of unforeseen situations, which obliged us to develop new skills and strategies. In doing so, we also pushed the boundaries of clean technologies and renewable energies to unprecedented levels,” said Piccard.

The FAI has received three preliminary world record claims for Distance along a course, pre-declared waypoints (1487.6 km), Free Distance (1506.5 km) and Straight distance, pre-declared waypoints (1386.5 km) following Solar Impulse's flight from Phoenix to Dallas.

The solar-powered airplane Solar Impulse, which departed yesterday 22 May from Phoenix, reached Dallas this morning, thus achieving a flight that might prove to be the longest flight ever made with 1’541 km.

With this performance André Borschberg, who piloted the plane in this 2^nd leg of the Across America Mission, would supersede the record he himself established in 2012

All the data from the loggers must be now be provided by the Solar Impulse team to the National Aeronautics Association and then to the FAI for ratification. Observers from the FAI Amateur Built and Experimental Aircraft Commission (CIACA) were present in Dallas and at the Observation Centre in Payerne, Switzerland to collect the flight information. The Observers included CIACA President Alfons Hubmann.

“This leg was particularly challenging because of fairly strong winds at the landing. It also was the longest flight – in terms of distance - ever flown by a solar airplane. You have to understand that the pilot needs to stay awake for more than 20 hours without any autopilot” said André Borschberg, co-founder, CEO and pilot of Solar Impulse who still holds the record for the longest duration ever in a solar powered airplane with 26 hours.”
