Pilot error.
Pilot error.firing in a very high G turn? - Tenacious 1The opposite, I think.
Grumman Test Pilot Don Evans( http://www.grummanpark.org/content/don-evans-grumman-test-pilot--flight-no-8 but for some reason making a link to it doesnt work right)told of making the mistake of raising the nose of his Sabre and firing a clearing burst to validate his guns functionality on the approach of a combat situation.He then brought the nose back down - with the result that he overtook his own ammunition, as this article puts it, and damaged his own plane.
