One of the Flying Tigers (Hill, perhaps?) reportedly either ran out of ammo, or his guns jammed while chasing a bomber...he was so pissed at the thought of the plane getting away that he pulled even with the bomber's cockpit, and rammed his wingtip through the glass, killing the pilot. Bomber crashed, he nursed his P40 back to base missing 2 feet of wingtip. I'm wanting to say I read this in Boyington's book, and Boyington was well known for enjoying the sauce, especially before a mission, so take that with a grain of salt. Good story, though!
