Solar plane flies for two weeks!
A solar plane has smashed records by flying non-stop for 14 days.
The Zephyr was designed and built in the UK but this record-breaking flight took place in Arizona in America.
There's no space for a pilot or passengers, and the wings are full of batteries that are charged up by the paper-thin solar panels.
Not a single drop of petrol is used to fuel it, and this new two week flight has really got the aeroplane industry excited about the future.
The only downside is that if it's too cloudy the plane starts to run out of power because it needs sunlight to charge the engines.
But experts reckon one day it could be developed to make the planes that take us on holiday around the world.
