Solar Impulse 2 has once again taken flight, this time out of Dayton, Ohio, in the early hours of Wednesday morning.
The latest leg of the solar-powered plane's flight on its round-the-world trip should take 17 hours as it wings its way towards Allentown, Pennsylvania.
The plane took off after a setback on Tuesday. The journey had been postponed when the inflatable hangar deflated temporarily and grazed parts of the vehicle's delicate frame. That proved far less serious than the massive delays the mission suffered due to battery damage and other problems earlier in the plane's journey.
You can follow Solar Impulse's trip online, and if you are in the eastern United States today you may even be able to see the plane in the sky.
