At Freakonomics Blog, Steven D. Levitt has some commentary that most frequent fliers will appreciate. It includes this:
Finally, when they read the safety instructions at the beginning of the flight, they go through the whole song and dance about “in the unlikely event of a water landing…” and all the precautions in place to deal with that happening. My friend Peter Thompson did some research on this. At least going back to 1970, which by my estimation encompasses over 150 million commercial airline flights, there has not been a single water landing!
NewMexiKen particularly appreciates the water landing silliness on flights from Albuquerque to Phoenix, or to Denver, or to Dallas.
