I built a weather balloon kit and decided to send a brand new iPhone 7 while its recording into space without any case/protection.
There ended up being a massive jet stream from launch site so the iPhone traveled approx. 3 hours away and it took us another 3 hours to hike onto unknown mountains to retrieve this thing.
If anyone has any idea why the iPhone randomly shut off and stopped recording in space before it even reached burst altitude (100,000 ft.), comment below! It was a 128GB model so it should have captured the entire crash landing.
