I had an old neighborhood friend who at the age of 18, went with another friend out to the live fire impact range on fort lewis....apparently to look for cool military stuff that they could play with and harness the energy. They found it. My old friend found two 40mm grenades that had failed to detonate. He, apparently, placed both rounds into a coat pocket and at some point attemtped to cross a small ravine out on the range by jumping across it. When he landed on the other side, the jarring that occured by landing on the other side of the ravine did detonate both grenades simultaneoulsy.
He died insantly.
Was back in about 1978...maybe 79........made the evening news with Dan Rather. Was pretty pathetic. The kid had a dad in the army and was infatuated with all things that went "boom"
Play with fire and you will get burned eventually.
