Did you miss the first Round-the-World solar flight? Catch up!

We’ve done it! We accomplished the first ever Round-the-World solar flight: 40,000 km without fuel! A first in both aviation and energy history, with the goal of encouraging the implementation of clean technologies on the ground. For those of you who missed part or all of our incredible journey, here’s a little sum up with the most important moments and best of videos (enjoy). Don’t forget to re-watch the last and 17th flight of the journey, that was streamed live from the cockpit on solarimpulse.com.

For those of you who missed part or all of our incredible journey, here’s a little sum up with the most important moments and best of videos (enjoy):

Leg 1: Abu Dhabi — Muscat

Pilot: André Borschberg

13 hours and 1 minute — 772 km — 383 kWh. During the first flight of the Round-the-World adventure, Si2 crossed its first international border and André flew over the 1,300-meter high Al Hajar mountains.

Leg 2: Muscat — Ahmedabad

Pilot: Bertrand Piccard

15 hours and 20 minutes — 1593 km — 304 kWh. During this flight, Bertrand crossed the Arabian sea, Si2 set a world record for distance flown in a solar airplane: 1593 km, and became the first solar airplane to land in Asia.


Leg 3: Ahmedabad — Varanasi

Pilot: André Borschberg

13 hours and 15 minutes — 1170 km — 428 kWh. This flight took off late due to custom issues, and Bertrand also had some problems with his passport. Landing in Varanasi, the spiritual capital of India, had a special meaning for the pilots, and the press conference that took place there was one of the largest ever for the project.


Leg 4: Varanasi — Mandalay

Pilot: Bertrand Piccard

13 hours and 29 minutes — 1536 km — 397 kWh. Varanasi was a pit stop so the plane took off a few hours after having landed. During this leg, Bertrand broke the Solar Impulse speed record: 216 km/h and flew over the beautiful Ganges delta and Bay of Bengal.

Leg 5: Mandalay — Chongqing

Pilot: Bertrand Piccard

20 hours and 29 minutes — 1450 km — 440 kWh. Just after takeoff, Bertrand flew over the enchanting temples of Myanmar, lighted up at night. Si2 then crossed the Chinese border, flew over the Burmese mountains and had to land with strong wind on the runway in Chongqing.


Leg 6: Chongqing — Nanjing

Pilot: Bertrand Piccard

17 hours and 22 minutes — 1241 km — 325 kWh. The team had been stuck in Chongqing for three weeks as it was difficult to find a weather window to leave. This flight was used to prepare the Pacific Crossing, the toughest leg of the journey, and Bertrand took the first ever selfie in a solar airplane.

After waiting 21 days for this flight, the Nanjing team welcomes Bertrand!

Leg 7: Nanjing — Nagoya

Pilot: André Borschberg

44 hours and 9 minutes — 2852 km — 958 kWh. André was initially supposed to fly from Nanjing to Hawaii but the flight had to be rerouted to Nagoya because of bad weather conditions. It was the first time Solar Impulse 2 made it through one day and night of flight in a row.

Leg 8: Nagoya — Hawaii

Pilot: André Borschberg

117 hours and 52 minutes — 7212 km — 2409 kWh. It was the first time André spent several days in the cockpit and over an ocean. During these 5 days, he broke the world records for longest flight in a solar aircraft, longest free distance along a course, longest straight distance free flight, and longest solo flight in aviation history. After landing, the team found out that the batteries had overheated, preventing them from continuing the adventure before 2016.

Leg 9: Hawaii — San Francisco

Pilot: Bertrand Piccard

62 hours and 29 minutes — 4086 km — 1121 kWh. It was the first time Bertrand spent several days in the cockpit. During those three days, he talked with Ban Ki-Moon just after the ratification of the COP21 Paris Agreement, and flew over the Golden Gate bridge, as he had done during the Across America mission with Si1 in 2013. The mobile hangar had to be set up on Moffett airfield to house Si2.

Leg 10: San Francisco — Phoenix

Pilot: André Borschberg

15 hours and 52 minutes — 1113 km — 480 kWh. As he flew from California — the state of innovation — to Arizona — one of the states with the highest penetration of solar energy — André flew over the SpaceX airbase and the Mojave Desert, famous for its experimental aviation stories.


Leg 11: Phoenix — Tulsa

Pilot: Bertrand Piccard

18 hours and 10 minutes — 1570 km — 445 kWh. Tulsa was an unexpected destination, as the weather forced us to look for other cities than the ones that had been planned. Bertrand flew over Albuquerque, home to the largest hot air balloon festival in the world, which brought back the memories of his 1999 round-the-world balloon tour, before landing in the “tornado alley”. A dangerous part of the United States but through which we had to go to reach NYC.


Leg 12: Tulsa — Dayton

Pilot: André Borschberg

16 hours and 34 minutes — 1113 km — 460 kWh. That day was the 89th anniversary of Charles Lindbergh’s Atlantic crossing. After Tulsa, André landed in Dayton, the hometown of the pioneers whose flights gave way to modern aviation: the Wright brothers. The mobile hangar had to be set up in Dayton to protect Si2 during its stay there.


Leg 13: Dayton — Lehigh Valley

Pilot: Bertrand Piccard

16 hours and 49 minutes — 1044 km — 391 kWh. This flight was postponed by a day because the mobile hangar deflated on Si2 and a whole day of checks thus had to be made to be sure the aircraft hadn’t been damaged. Bertrand landed at sunset, rather than the usual night landing, which offered the public a beautiful view. Arriving in Lehigh Valley brought Solar Impulse to the gates of NYC.


Leg 14: Lehigh Valley — New York City

Pilot: André Borschberg

4 hours and 41 minutes — 265 km — 0 kWh. It was the first takeoff of the 2016 adventure that we had to postpone after having already taken the plane outside. But the second time was a charm and André was able to fly over the Statue of Liberty, something he’d been dreaming of for years as the 2013 flyby had been cancelled due to administrative reasons. This flight was the shortest of the adventure and completed Si2’s crossing of the United States.

Leg 15: New York City — Seville

Pilot: Bertrand Piccard

71 hours and 8 minutes — 6765 km — 1388 kWh. After 3 days of flight, Bertrand achieved the first transatlantic solar and electric crossing, following in the footsteps of Charles Lindbergh. While Bertrand Piccard flew alone over the ocean, and talked to Richard Branson, André was at the Mission Control Center for the first time during a flight. Si2 was welcomed back to its home continent by a colorful flight formation from the Spanish Patrulla Águila.

Leg 16: Seville — Cairo

Pilot: André Borschberg

48 hours and 50 minutes — 3745 km — 808 kWh. After having taken off, André flew over Gemasolar in Spain, the first solar plant to produce energy day and night. It was the flight during which Si2 crossed the most airspaces so far: the Mediterranean Sea, Tunisia, Algeria, Malta, Italy, Greece and finally Egypt. For his last flight of the Round-the-World adventure, André flew over the 4,000 year old pyramids, one of the 7 wonders of the world.

Leg 17: Cairo — Abu Dhabi

Pilot: Bertrand Piccard

48 hours and 37 minutes — 2694km — 917.9 kWh. We made it back to Abu Dhabi! By landing back in Abu Dhabi after a total of 21 days of flight travelled in a 17-leg journey, Si2 has proven that clean technologies can achieve the impossible.

Beyond this historic milestone, the two Swiss pioneers will continue to urge the global implementation of energy efficient solutions through the creation of the International Committee for Clean Technologies and leverage the expertise and technology gained over the years in Solar Impulse by launching new innovative projects, such as the development of solar powered drones. And more… keep posted!
