> Oh, and 727s require three people to properly fly them.

3 people to safety fly them. I doubt the plane shuts off if three life-signs aren't detected.

Pieces are going to be found on the ocean floor in some decades in a random sonar survey of the bottom for a new pipeline, I guarantee it.

Commercial applications like this are the only reason to do large area bottom surveys.
