Nah, we've all been there; my bad day was when we decided that, when loading a CL44 at DXB with gold bars, we would set up a system where the gang of 20 or so loaders would each collect a bar in turn from the truck near the nose, ascend the front steps, walk down the aircraft, stow the bar in a tie down container (10 bars per container, or something like that, as I recall) starting from the rear of the aircraft, and then walk down the back steps and collect another bar.
The elegant raising of the nose as the "critical coolie" reached what I hesitate to call the tipping point and continued rearwards, now downhill, was beautiful to watch, but unintended. What did for us was "starting from the rear of the aircraft".
