St. Louis Chosen for Midwest Stop During Historic Solar Impulse Flight

The flight plan also includes stops at Phoenix Sky Harbor, Dallas-Fort Worth, Washington DC-Dulles and New York's JFK, where it will conclude its historic journey without using a single drop of fuel.


This revolutionary carbon fibre airplane has the wingspan of a Boeing 747 (63.4m / 208 ft) and the weight of a small car (1,600kg / 3,527 lb). It is the result of seven years of intense work, calculations, simulations and tests by a team of about 80 people and 100 partners and advisors. A plane so big and light has never been built before. The 12,000 solar cells built into the wing provide four 10HP electric motors with renewable energy. By day the solar cells recharge the 400kg / 881 lb lithium batteries which allow the plane to fly at night.
