Solar Impulse 2 – a solar powered aircraft – started the first round-the-world solar flight on March 9 and will fly over Bangladesh tomorrow evening if everything goes as planned, says a press release.

Swiss pioneers Bertrand Piccard and André Borschberg aim to become the first humans to fly around the world in a solar-powered aircraft.

The aircraft is designed to remain airborne day and night without using a drop of fuel. The plane's exceptional aerodynamic performance and energy efficiency (three times greater than commercial aircraft) make this possible.

A team of technicians and scientists from Swiss Federal Institute of Technology Lausanne worked together on this ground-breaking project, the press release added.

This first round-the-world solar flight involves landings in Oman, India, Myanmar and China before crossing the Pacific Ocean. It will then stop-over in the United States and finally cross the Atlantic Ocean, heading for southern Europe or North Africa and to its point of departure.

Solar Impulse is a campaign for more sustainable use of resources. It aims at demonstrating that with clear vision it is possible to go beyond what is currently thought to be possible.
