Years ago in Japan, we spotted a special safety vest for construction workers that inflated in the event of a fall to protect their bodies. Turns out the technology, which amounts to a personal, wearable airbag, has finally found its way to the 'States; motorcyclists use the Impact Jacket to protect them in crashes.
Also turns out it works--Maryland motorcyclist Joseph McPhatter was the first (involuntary) rider to use the jacket in a crash, as he flew 100 feet through the air and hit the pavement at an estimated speed of 140 miles per hour. His injuries were minor.
Cool, no? And now some small, collegiate part of us desperately wants to deploy the Impact Jacket during a bar brawl.
