During the 1982 Falklands war British pilots reported that penguins toppled over backward while gazing at the planes. British navy pilots were then banned from flying low over penguin colonies. It led to a UK government study of the penguin-toppling effect. For seventeen days two helicopters were flown from varying directions and heights over the penguins. The result? Penguins do not topple over while gazing at aeroplanes.

That cracked me up! *sigh* thoes brits...
