2013 – The first Solar Impulse aircraft, HB-SIA, the world's first solar-powered aircraft capable of operating day and night, completes the first leg of its attempt to become the solar-powered aircraft to fly across the contiguous United States, landing at Phoenix Sky Harbor International Airport in Phoenix, Arizona, at 12:30 a.m. PDT after departing Moffett Field in Mountain View, California, at dawn on 3 May and covering 1,203 km (747 miles) in 18 hours 18 minutes at an average speed-over-ground of 65.5 km/h (40.7 mph).
