August, that has to be the most impressive response to a smarty-pants comment I've ever seen -- now I'm tempted to resurrect my SLR equipment.
I also learned, from this and the Cobra Den threads, about Pinball P-63's, never knew anything about 'em. From Wikipedia:
"Pinball" operations -- Its main use in American service was the unusual one of a manned flying target for gunnery practice. [citation needed] The aircraft was generally painted bright orange to increase its visibility. All armament and the regular armor was removed from these RP-63 aircraft, and over a ton of armored sheet metal was applied to the aircraft. This was fitted with sensors that would detect hits, and these hits were signaled by illuminating a light in the propeller hub where the cannon would have been. This earned the aircraft the unofficial nickname of Pinball. Special frangible rounds made of a lead/bakelite combination were developed that would disintegrate upon impact...."
Say what? Oh....
"A material is said to be frangible if through deformation it tends to break up into fragments, rather than deforming plastically and retaining its cohesion as a single object. Common cookies or crackers are examples of frangible materials, while fresh bread, which deforms elastically, is not frangible."
So next time I cook breakfast for an English major I'll ask "do you prefer your bacon frangible, or elastic?"
