Stones - He had them.

From It Don't Make Sense,  the story of WWII pilot William Overstreet, Jr., who gained immortal fame for chasing a German ME-109 he was dogfighting with under the Eiffel Tower.

The story is as follows:

In the spring of 1944, Bill Overstreet of the 357th Fighter Group stayed hot on the tail of a German 109 ME 109G. The German pilot flew over Paris hoping the heavy German anti-aircraft artillery would solve his problem and eliminate Overstreet and his P51C, the “Berlin Express.” Hoping did no good. The German’s engine was hit, and Overstreet persisted through the intense enemy flak. As a last resort, the ME109 pilot aimed his aircraft at the Eiffel Tower and in a breathtaking maneuver, flew beneath it. The unshakeable Overstreet followed, and scored several more hits in the process. The German plane crashed and Bill escaped the heavy flak around Paris by flying low and full throttle over the river.
Overstreet describes the heroic event in his own words:
“I had followed this 109 from the bombers when most of the German fighters left. We had a running dogfight and I got some hits about 1500 feet. He then led me over Paris where many guns were aimed at me. As soon as he was disabled, I ducked down just over the river and followed the river until I was away from Paris.”

Certainly the main benefit of this act was to inspire the French Resistance on the ground in occupied Paris.  They had to know that the Germans had caught a tiger by the tail in this American.
