    LEG #5: Takeoff MANDALAY - CHONGQING
    March 30, 2015: The solar aircraft departed from the Mandalay International Airport this morning at 3:36 am local time (9:06 pm GMT [March 29th]) attempting the most challenging flight since having started the Round-The-World journey, to reach Chongqing (China). The anticipated 19 hours of flying time and 1,375 kilometers of distance covered will be physically demanding, due to the prolonged use of oxygen required in the unpressurized cockpit, in which I will face temperatures descending to minus 20 degrees celsius. The flight will be demanding with respect to the steep ascent and limited time allowed for high altitude preparation as Solar Impulse 2 (Si2) will fly over the Himalaya mountains. Si2 is subsequently expected to remain at a flying altitude of roughly 7,300 meters during the majority of the flight.

    Speech to the President of Myanmar
    I made a speech to the President of Myanmar expressing how important it is for André Borschberg and I to have the opportunity to stay in Mandalay the next few days. The 21st century is about exploration and adventure but this time around in terms of quality of life rather than conquest of the world.

    LEG #4: Landing VARANASI - MANDALAY
    I landed HB-SIB at the Mandalay International Airport in Myanmar at 19:51 lical time or 13:21 UTC, completing the 4th stop on the Round-The-World route. Flying from Varanasi (India), it took the pilot 13 hours and 29 minutes to arrive in Myanmar where the team of Solar Impulse and the Si2 aircraft will stay for at least 3 days. From the cockpit, just before the descent of Si2 into Mandalay, I was welcomed by a warm message from the President of the Republic of the Union of Myanmar, H.E. U Thein Sein, delivered by U Win Swe Tun, Director General, Department of Civil Aviation, Ministry of Transport. Piccard also spoke with Serge Pun, Chairman of First Myanmar Investment and Yoma Strategic Holdings, Si2’s Local Partner. This destination was chosen to demonstrate the potential of clean technologies. This was an other record-breaking flight in terms of speed as Si2 reached a ground speed of 117 knots due to tail winds.

    LEG #4: Takeoff VARANASI - MANDALAY
    After a short pit-stop to change pilots before taking off for its fourth flight to Mandalay (Myanmar), I took-off  at 5:22 local time (23:52 UTC). This flight will allow me to test the stabilisation and augmentation system, as well as the oxygen as he climbs up to 27,000 feet. Landing is estimated to be at 7:30 pm local time (1:00 pm UTC). I was really looking forward to this flight because when I attempted to go around the world in a balloon, I failed and had to stop in Myanmar. Now I am coming back with a solar airplane, and on top of this, my daughter I haven't seen for the past month will be there at the landing. We will stay at least two days in Myanmar before continuing to alternate flying the zero-fuel airplane around the globe. Over the coming months, we will stop in China, USA, Northern Africa or Southern Europe before returning to Abu Dhabi to complete our circumnavigation of the world.

    Monaco Mission Center
    The official opening took place on February 10 2015 of the Monaco Control Center (MCC) for the first round-the-world solar flight attempt by Solar Impulse, a project initiated by Swiss pilots Bertrand Piccard, Initiator and President of Solar Impulse, and André Borschberg, co-founder and CEO. Drawing on the personal commitment of H.S.H. the Sovereign Prince and Monaco's exemplary commitment to sustainable development and the promotion of renewable energies, the Government of Monaco have chosen to support, alongside the Prince Albert II of Monaco Foundation, the Solar Impulse initiative by housing the mission control center (MCC) on Monegasque territory in the Rainier III Auditorium and Congress Centre throughout the duration of the world tour.   The Monaco Control Center is now operational for the launch of the world tour (see details of the route in the annex), and ready to welcome the team of over 40 people to the facilities specifically fitted out for this adventure. (See details of the team's skills and expertise in the annex). H.S.H. Prince Albert II of Monaco stated: "Solar Impulse is first and foremost a quest for clean energy, capable of flying an aeroplane around the world without harming the environment; an energy capable of conquering the skies without damaging the earth. This project helps to show that the new low-carbon economy which the world needs is today possible, provided that we are fully committed to it, with passion, tenacity and inventiveness. This is why more than ever we need to promote research and innovation, as you are doing and as we are doing here in Monaco by hosting your project and supporting many others with the Monegasque State as well as with my Foundation".  The Monaco Control Center plays a key role in the implementation and execution of the project: it is here in this room that all the information needed will be collected and processed for us to configure the flights, follow the aircraft's battery level indicators, guide the pilots with their itinerary and stay in permanent contact with them via satellite communication. "The Monaco Control Center will be the only place, other than the stopovers, where the public, media, VIPs and partners will be able to follow the Solar Impulse adventure when the plane is in flight" explained Bertrand Piccard, "and the fact that Monaco has been selected results from a long-established friendship with Prince Albert II who, in addition to being a patron of Solar Impulse, is one of the only Heads of State to champion environmental protection at all political discussions." Solar Impulse 2 and the two pilots who will take turns flying the aircraft at every stage, will also pass on to the MCC all the information recorded during flights: which will enable us to know exactly the status of the aircraft and its position. For André Borschberg "the MCC is an essential link for the success of Solar Impulse's round-the-world tour. This is where the decisions will be made for the departure and routes of each stage. It is via the MCC that the pilot will be in contact with the whole world. Monaco has provided us with the ideal infrastructure together with all the support necessary, the professionalism and outstanding welcome that characterise the Principality. At the same time, the MCC is coordinating the support team which will be following Solar Impulse throughout its world tour and will be in permanent contact with the CAA (Civil Aviation Authority) and the IAF (International Aeronautical Federation).  It will operate 24/7 from the initial take-off to the final landing of this 12-stage world tour. The voyage undertaken by Solar Impulse 2 is a pioneering attempt in the history of world tours: a way for the partners of this exploration to show how a spirit of innovation together with clean technologies can change the world. The aim of this adventure is to promote innovative technical solutions in order to combat climate change and support governments in their commitment to implement more ambitious energy policies.

    Unveiling of the Round-The-World Route
    Solar Impulse 2 (Si2) will take-off from Abu Dhabi, crossing two oceans and four continents, to complete its round the world flight. Bertrand Piccard and André Borschberg, the Swiss co-founders and pilots of Solar Impulse, along with their Partners, today revealed the detailed global flight route of Solar Impulse 2 (Si2). The first solar-powered plane able to fly day and night will land in 12 locations across the world and travel 35,000 kilometres in the first attempt to fly around the globe without using a drop of fuel. For pilots Piccard and Borschberg, the drive behind their mission is to demonstrate how clean technologies and a pioneering spirit can change the world. Si2 will take-off from Abu Dhabi, capital of the United Arab Emirates, in late February or early March and return by late July or early August 2015. The route includes stops in Muscat, Oman; Ahmedabad and Varanasi, India; Mandalay, Myanmar; and Chongqing and Nanjing, China. After crossing the Pacific Ocean via Hawaii, Si2 will fly across the Continental U.S.A. stopping in three locations – Phoenix, and New York City at JFK. A location in the Midwest will be decided dependent on weather conditions. After crossing the Atlantic, the final legs include a stop-over in Southern Europe or North Africa before arriving back in Abu Dhabi.

    SOLAR IMPULSE 2 FREIGHTED TO ABU DHABI
    On 6th January at 08.24, Solar Impulse left Payerne, its base since February of last year, to fly to Abu Dhabi. It was in the belly of a Cargolux Boeing 747 that the solar airplane took off for the capital of the United Arab Emirates, in preparation for the launch of its attempt to fly round the world, planned for March.   With the help of Cargolux, Swissport, Welti-Furrer, and the Army’s Logistics Base (BLA), about thirty people were involved in loading the aircraft, which had landed late the previous afternoon. The process lasted late into the night and proved to be both complex and delicate, especially finding room in the wide-body for some twenty-five separate components. The trickiest part of the operation was positioning the fuselage and the 72-meter-span wing,  disassembled into three sections that could fit into the aircraft’s hold.   In the end, everything went well. The operation was also a very moving moment. It was not just Si2 leaving Switzerland, but a whole phase coming to an end, so that now the long-awaited round-the-world flight can start. The entire Solar Impulse team is very grateful for the support received from the Municipality of Payerne, and the Swiss Accident Investigation Service (SESA), and cherishes the friendships that have formed during this long period of preparation. Having staged through Basle, the freighter arrived in Abu Dhabi at 19.04 local time (GMT+4).   Photos of the operation are on line.

    NEW YORK - CLIMATE SUMMIT 2014
    Bertrand Piccard and André Borschberg were just two of the delegation that included 120 Heads of State and Government, and over 800 leaders in business, finance and civil society responding to Ban Ki-moon's invitation. The spirit of the summit resonated around the world, including a gathering of 300,000 supporters in the streets of New York. The political momentum has gained since the Copenhagen Climate Change Conference in 2009: while previously the delegates only recognized the existence of the problem, the summit in New York saw a more positive and determined commitment to financing low-carbon development and the adoption of clean technologies. Indeed, a fund of $200bn was agreed by a coalition of global leaders. “The only way to motivate people is to demonstrate the existence of solutions, not only to speak about the problem,” said Bertrand Piccard. “It was great to meet so many people acting to change the world,” continued André Borschberg. The Solar Impulse founders announced Abu Dhabi as the host city, and Masdar as the host partner while standing alongside Didier Burkhalter, President of the Swiss Confederation, His Highness Sheikh Abdullah Bin Zayed, UAE Minister of Foreign Affairs and Dr. Sultan Ahmed Al Jaber, Chairman of Masdar. Bertrand and André were pleased to be back in New York just a year after completing their flight across America with Si1, the first generation Solar Impulse airplane. Their record-breaking journey in 2013 visited the cities of San Francisco, Phoenix, Dallas, St. Louis, Cincinnati, Washington and New York. Second generation Si2 will look to make stopovers across the USA as it attempts the first Round-The-World solar flight, commencing in March 2015. The summit was really a positive time to develop the momentum for meaningful change in developing and adopting clean technologies, of which Solar Impulse is a pioneering example. The first Round-The-World solar flight will be bracketed by the forthcoming summit in Lima, later this year, and the United Nations Climate Change Conference in Paris at the end of 2015.
