That's not the same thing as saying that it cannot occur, though.

Fer cryin' out loud, of course anything can happen. And yet we still
allow planes to takeoff.


If we did
have a wreck caused by such an unfortunate and unlikely event, would the
rules be changed?

Probably, because that's how the FAA works. Controller forgets
Metroliner on runway at an intersection at night, clears 737 to land,
which promptly lands on Metroliner. As a direct result I am no longer
allowed to put aircraft in postion at an intersection at night.


If so, why wait?

Because it's reasonable to wait.
