To recover the phone after surviving winds of 160 Kmh, temperatures close to 60º below zero and a fall that reached speeds of 240 Kmh even with the parachute deployed, Luke used the built-in GPS to transmit his coordinates to locate it (curiously, not too far from the launch site).
It took 72 minutes for the balloon to reach the height limit in the stratosphere, but unfortunately the phone ran out of battery with two minutes to go before landing because of the extreme cold. No one dares to record the Earth from space with their fourth-generation iPod touch?
