After 9 months having puttheir round-the-world flights on hold because of a battery complication during the 5 day/night flight from Nagoya to Hawaii, Impulse team was able to resume their attempt to accomplish  this historic journey.

They announced takeoff from Kalaeloa Airport on April 21st at 3PM UTC. Last week they declared Mission Mode and this week they have found a weather window that would give way to a 62 hour flight to reach Moffett Airfield, Mountain View, California, USA. The Solar Impulse support team will also be leaving Hawaii just after Bertrand Piccard takes off with Si2 in order to meet him on the other side.

You watch it all happen live, here.

Solar Impulse is not the first solar airplane, but it is the first to fly day and night, without any fuel, only using energy stored in its batteries.

The wing span of a Boeing 747 Jumbo Jet, the weight of a family car, the power of a small motorcycle, it is the largest aircraft ever built with such a low weight.
