When Apple first unveiled its iPhone 4 smartphone last summer, most media and bloggers were in agreement that the new glass construction was stunning. They also agreed, however, that the iPhone 4 would likely be more prone to significant damage than other smartphones due to the fragile nature of glass compared to plastic and metal. While we’ve heard our fair share of shattered iPhone stories, U.S. Air Force Combat Controller Ron Walker’s tale should help dispel the notion that the iPhone 4 is inherently fragile. While leaning out of an airplane looking for landmarks, Walker’s Velcro pocket flap popped open and his iPhone 4 plummeted to the earth below. At the time, the plane was traveling at 150 m.p.h at an altitude of roughly 1,000 feet. Once on the ground, Walker told a few friends what had happened, one of whom installed Apple’s “Find My iPhone” app on his own handset in an attempt to locate Walker’s lost phone. Unexpectedly, the app found Walker’s iPhone immediately and when the men drove to its location, they found the smartphone in perfect working condition without a scratch on it. Walker kept his iPhone in a standard Griffin case and it had no other casing or special protection at the time of its fall.
