Narrative:
During the copilot's walkaround; he saw that the mechanics had just discovered that at some previous maintenance point someone had left 29 screws out of a panel that requires 35 screws. This was on the left engine pylon. I remember that the engine fell off the DC10 because someone went on break; or was it a shift change? As the captain; I really don't want parts breaking loose and hitting the airplane or someone on the ground.
