The Solar Impulse 2 crew says the plane will leave Tulsa early Saturday morning.
Pilot André Borschberg will take off from Tulsa International at 4 a.m on May 21 , 2016. He will fly the solar-powered plane to Dayton, Ohio.
The pilots had hoped to leave town Thursday, May 19, but had to postpone the departure because of bad weather.
The crew says mission engineers in Monaco have found a path clear of bad weather that will allow Borschberg an 18-hour window to fly to Dayton. Dayton is where the Wright Brothers built some of their first airplanes.
The airplane landed in Tulsa late on the night of May 12. 2016. It was then moved to an American Airlines hangar where hundreds of people signed up to see it last Sunday and Monday.
The Solar Impulse 2's journey will take it to New York and from there, it will fly across the Atlantic Ocean.
