Back in June 2013, Bryan Chan and his four friends lost their GoPro after using a balloon to send it 98,000ft high. Two year later, the team got a phone call from a woman who found a strange box with their names on it. In it was the camera and all of the original images still intact.
The team were even more amazed when they viewed the long-lost footage, which showcases spectacular views of the Grand Canyon from the edge of the stratosphere. Watch the video below.
