Holy cow, I wrote a book!
Everyone has read the story about penguins
falling over backwards while observing low-flying aircraft.
The Annals of Improbable Research reports
Dr. Richard Stone has been
researching the ecological effects of helicopter overflights on King penguins
and his preliminary results show that
King penguins do not, in fact, fall over backwards (or forwards or even sideways)
when you fly over them.
On the other hand, low-flying aircraft do create distress among the
penguins; Dr. Stone recommends a minimum overflight altitude of 1000 feet.
