McDonnell Douglas may have crafted an interceptor with a perfect kill-to-loss ratio, but that doesn’t mean the F-15 Eagle has never crashed due to reasons other than enemy fire. A total of 175 aircraft have been lost since it first flew in 1972, 123 of them by the US Air Force (USAF), its primary operator.
