The document discusses the Solar Impulse project, which aims to develop a manned solar-powered aircraft capable of flying day and night using only solar power. Solar Impulse 1 was an experimental solar-powered aircraft developed by Solar Impulse that conducted its first flight in 2009. It had a wingspan of 63.4 meters and could carry one pilot for up to 5 days with its battery power. The document also answers common questions about the pilots' endurance, training, living conditions in the cockpit, and contingency plans in case of emergencies over open water.

6. FAQs
1. How long is one pilot in the air?
Five days. This is how long the plane will take to cross the Atlantic.
2. How were pilots trained?
Both pilots went through intensive training, including in yoga and self-
hypnosis.
3.How do the pilots live in the cockpit, go to the toilet?
They eat, sleep, drink and even go to the toilet. Short naps are also
possible.
4. Can the pilots sleep?
Only short naps when the plane is stable. In emergencies, seat starts
vibrating.
5.Can the aircraft fly on autopilot?
It has an electronic co-pilot, which can help the aircraft hold course. It
can be used inshort spells when a pilot is resting.

7. 6. Where's the mission control?
The mission control is located in Monaco . 65
ground staff travel with the pilots.
7. What happens if something goes wrong while
crossing the ocean?
The pilot would bail out and use ocean survival
gear to stay alive until rescue arrives.
