As a flier and Air Force chief of safety, fall migration season means one thing to me – our aircrews are at a dramatically increased risk of experiencing a bird strike.
Bird strikes cost the civilian and military aviation industry about $650 million a year. According to statistics maintained by the Safety Center’s Aviation Safety Division, the Air Force reported 64,946 strikes between 1995 and 2010, costing a total of $527 million. In 2010 alone, 4,723 reported bird strikes resulted in $22.5 million in damages, including $10 million to an F-15E following engine ingestion of a Black Vulture.
Most bird strikes occur below 3,000 feet, just as pilots are in initial climb or descent for field approach. My own “There I was” story began at approximately the same elevation. I wrote about that experience in the winter 2010 issue of Wingman.
For my last flight as the 19th Air Force commander I planned what I thought was a low-risk sortie in a T-38 from Randolph AFB, Texas, to Columbus AFB, Miss. Once airborne, I checked my wingman and he looked good. Just as I looked forward again, I saw a flock of birds and heard several simultaneous thumps.
My wingman confirmed exactly what I feared – a flash fire from my right engine exhaust; the engine was gone. I took the next couple of seconds to decide how to respond to the emergency. I called upon all my experience in the cockpit as well as all the emergency simulator training I’d received throughout my career. I completed all the appropriate checklists for multiple possible outcomes. A sudden weather change compounded the challenge, but I continued to use my training to counter each new predicament. I landed and was able to stop the aircraft about 1,000 feet from the end of the runway.
Relying on training and experience-based skills is a pilot’s first line of defense when things go terribly wrong. This includes handling an aircraft damaged by a bird strike. Risk management and hazard avoidance planning prior to launch can also help keep a pilot from being in a position of dealing with a worst-case scenario.
Extraordinary new technology provides credible information about migratory patterns and activity which has become an important reference when mission planning. Bird detection radar, better strike reporting processes, robust wing-level mitigation programs and increased partnering with local communities that surround our airfields has done much to help fliers avoid potential bird strikes.
The Safety Center’s Bird/Wildlife Aircraft Strike Hazard (BASH) team is the Air Force’s POC for worldwide on-site technical assistance. The team’s depth of knowledge and expertise are recognized around the world and they are frequently called upon to provide everything from technical analyses to guidance on establishing a BASH program.

Bird strikes happen. Because we can’t prevent them all, it’s imperative that we understand the risks and know the tools available to reduce risk as much as possible.
