We don't endorse any products; just try to present unbelievable side stories that yield practical knowledge. OK. Raise your hand if you have lost a portable device from a three feet-or-less fall from a surface in the last couple of years?? OK! That's a lot of hands today. And we would never bail from a plane unless we absolutely needed to {even on the tarmac-we think we have a cool link}, but if you are in the skydiving community, this device might sell itself. You have to read the CNN link to see the back story that many hated this phone {CNN actual photo of the 'after' phone above}, and a Consumer Reports reporter actually actually joked that the diver had [said with joking intent] finally fixed constant antenna/reception issues by dropping it from the plane as a 'proved method' of relief/satisfaction. No..even we can't make this up..http://www.youtube.com/watch?v=Zohc7PNP-pw&feature=related {A fighter pilot that needed reliable communications, too...'Misty One' brings in a crippled plane with a flaming #2 engine safely down to the tarmac, ultimately ejecting moments before the runway ends and the plane splinters. This discipline meant the plane was not falling, uncontrolled, into civilian areas, but was an unbelievable controlled crash. And talk about durable technology-notice how the on-board flight computer stays on long enough to tell the now disintegrated-into-fragments plane that it is 'bingo'/out of fuel}.
