For the birds Published March 3, 2003 WHITEMAN AIR FORCE BASE, Mo. (AFPN) -- A B-2 Spirit sits in the background here as U.S. Department of Agriculture Wildlife Services employees Todd Stewart and David Borrowman inspect a propane cannon on the airfield. The cannon is a nonlethal way to remove wildlife, especially geese and birds of prey, from the airfield. Wildlife found on or near the runway can cause hazards for aircrew and aircraft. The cannon is fired daily by airfield management and is visually checked by Bird Avoidance Strike Hazard program team members to ensure it is in working order. (Photo by Staff Sgt. Francesca Popp)
