One of my friends in High Schools Dad was in the air force researh branch and ended up with a lot of toys from aircraft manufacturers. Lockheed gave him a few of these when he went to visit them as a novelty item in a bag of presents. Some went off when they hit a wall, some had sound. They were neat, but I don't plan on buying them.
I could never figure out why they gave them to an AF General and not a USMC or Army.
