BRIDGETON, Mo. (KSDK) - The public is invited to check out aviation history first hand.

The Solar Impulse plane landed at Lambert-St Louis International Airport just after 1:00 a.m. Tuesday as part of its cross-country two month long trip.

The plane took off from Dallas-Fort Worth International Airport Monday morning and it took 21 hours to reach St. Louis. The plane flew at 50 miles per hour.

People can tour the solar powered plane for free on Thursday. You can register for free tickets online.

The solar-powered plane has 800 pounds of batteries on board that are powered by the sun, so the plane can continue to fly in the dark and run on battery-power.

A planned exhibit has been scrubbed because of the storm damage at the airport Friday. The solar plane used its own prototype inflatable hangar after it first arrived.A metal hangar will be constructed for hte public viewing this week.
