I removed myself from an airline flight - long

"Robert Moore"

The ground crew has a lot more training and experience with
the cargo doors than does the flight crew. Airlines have
specialist to work on each task and if I recall correctly, at
one time, one of the major airlines even had a line maintenence
foreman doing the aircraft pre-flight inspection instead of the
flightcrew.
Airline pilots are just that, pilots, they are not trained to
do the work of a maintenence crew.

That's exactly what the crew communicated to me (my quotes were from memory
but the sense I left the cockpit with was exactly what is said above).

Looking back, what happened was that I truly was spooked for a few minutes.
Once spooked, I reasoned to myself that I'd be a fool not to pay attention
to the fear.
