(Similar procedure - fire 'em out of a cannon into the turbine blades and film at high speed so you can watch it get sliced into cold-cuts.) The specification may well apply to canopy impact tests also since it would be seeing similar takeoff/landing profiles. I hear the Navy has it's own standard for bird-ingestion. The birds that follow aircraft carriers are apparently larger than a Mark One/Mod Zero Air Force bird.
