The Solar Impulse is on the ground at Lambert Airport.
The solar-powered airplane took off Monday morning from Dallas-Fort Worth International Airport bound for St. Louis -- some 560 miles away. The plane landed at Lambert about 1:30 Tuesday morning.
The project was aimed at building a solar-powered airplane that could fly day and night without fuel. They succeeded with a 21-hour 21-minute flight to St. Louis, the longest so far for Solar Impulse.
The storms that swept through St. Louis Friday night damaged a hangar that was going to house the plane while at Lambert, and that created another opportunity for the Solar Impulse team. They deployed the plane's own inflatable hangar for the first time during a mission. The revolutionary, ultra-light structure was designed for use during their planned flight around the world in 2015.
