As part of the Bird Aircraft Strike Hazard program, bird spikes were set to prevent birds from perching on the approach lights at Joint Base Langley-Eustis, Virginia. The BASH Program uses several methods, including propane cannons, non-lethal pyrotechnics and sound emitting equipment to keep wildlife off the airfield by making it undesirable in terms of food, water and shelter.
