Listen now (30 min) | When the United States Air Force tests a new aircraft it needs to make sure it won't crash should a stray bird slam into the plane's side.

The chicken gun allows the military to make sure no stray bird will foul up its expensive jets while they're mid-flight. If you think the chicken gun is weird, it’s only the tip of a strange and fascinating iceberg.
