Ellsworth Air Force Base Uses Cannons to Prevent Bird Collisions
29 Oct 2018
RAPID CITY, S.D. — An Air Force base near Rapid City has unveiled a new cannon system designed to prevent costly collisions between bombers and birds.
The Ellsworth Air Force Base has implemented a new $150,000 bird abatement system, which is comprised of a rotating cannon and a 20-gallon propane tank, the Rapid City Journal reported. Igniting a small amount of propane into the cannon produces a shotgun-like sound, which scares birds off.
