Never thought about that before. However, my guess is that it is to make
sure that aircraft insurance requirements as to minimum runway lenght for
certain types is exceeded rather than simply met.

Anybody else?

Can anyone explain why runway lengths are sometimes "X thousand and
ONE feet" in length? I was just looking through a list of Iowa's
approximately 110 airports and 7 of them have runways that are "X
thousand and one feet" long.

Do runway manufacturing companies offer special deals like "Buy 5,000
feet of runway, get your next foot free!!!"

There's got to be a logical explanation - anyone know it?
