The Solar Impulse aircraft took off on its fifth and "most dangerous leg" of its round-the-world trip yesterday.
It departed from Mandalay International Airport and will fly 19 hours and 1,375km to Chongqing, in China.
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 mountains at the beginning of the flight.
Si2 is subsequently expected to remain at a flying altitude of roughly 7,300m during the majority of the flight.
Pilot Bertrand Piccard will face an unpressurised cockpit and temperatures of -20°C during the flight.
One of the aircraft’s solar cells is damaged, reducing its capacity to capture solar energy by two per cent, but it is still able to fly safely.
