In 2013, a group of friends got together to launch a balloon to the edge of space to take photos and video footage of the Grand Canyon.
With a custom designed and 3D printed chassis, the group included a Go Pro camera and camcorder for the video footage and a Samsung mobile phone for photographs and crucially – as the GPS tracker.
Sadly for them, the phone never registered a signal again on it’s route down, so they never received a signal to let them know where the balloon has landed and where they could find it again – as it turned out, 50 miles away.
fast forward two years and an AT&T employee was hiking through the desert when she stumbled across the remnants of their experiment. She took the phone into her local AT&T store where they established the owner of the sim card within the phone and the group finally got hold of the footage they thought was lost for ever.
