New York, US (BBN)- A plane powered entirely by the sun is flying over New York City.
The Solar Impulse 2 took off from Lehigh Valley, 87 miles (140km) west of the "Big Apple", on a journey that takes only a few hours, reports BBC.
The flight marks the completion of the trans-America portion of the aircraft's bid to circumnavigate the globe.
The solar-powered plane is arriving on the east coast of the US, ready for a daunting crossing of the Atlantic.
The plane flew over the Statue of Liberty for a pre-arranged photoshoot, and is due to land at John F Kennedy airport in the next airport.
Pilot Andre Borschberg is at the controls for this flight. His business partner Bertrand Piccard will take over for the Atlantic leg.
Deciding when to cross the ocean will be a tricky decision. The slow-moving, ultra-light plane needs benign winds, and the team concedes that the right conditions may not present themselves for several weeks.
The project has made excellent progress since renewing its global challenge in Hawaii on 21 April.
In 2015, Solar Impulse flew eight stages from Abu Dhabi to Kalaeloa, including a remarkable four-day, 21-hour leg over the western Pacific - the longest flight in aviation history in terms of the time it took.
It was damage to its batteries on that stage, however, that forced Solar Impulse to lay up for 10 months, for repairs and to wait for optimum daylight length in the northern hemisphere to return.
The quest will be complete when the plane arrives back in Abu Dhabi.
The Solar Impulse plane is covered in 17,000 photovoltaic cells.
These either power the vehicle's electric motors directly, or charge its lithium-ion batteries, which sustain the plane during the night hours.
It is intended as a demonstration of the capabilities of solar power.
