I have recently been featuring global adventures, and a month ago reported on the around the world odyssey of the Solar Impulse 2, which left Abu Dhabi on March 9.
So far, the longest leg from Mandalay to Chongqing took 20.5 hours. Remember, the plane is powered only by photovoltaic cells, which needs the Sun.
The Solar Impulse 2 has a wingspan wider than a Boeing 747, but only weighs as much as a Ford Fiesta sedan:
The 62-year-old Mr Borschberg, who trained as a fighter pilot in the Swiss air force, will face extreme temperatures in the unpressurised and unheated 3.8-cubic-metre cockpit.
The plane’s autopilot function allows for no more than 20 minutes of rest at a time, pushing the limits of human endurance as well as the boundaries of science.
