imagine what could happen if an empty cargo container got hefted across the apron - it could easily kill people.
That exact incident happened at my company about 5 years ago.
777F landed at PANC, was given a gate requiring two right turns. They shut down the right engine after cooldown.
After that, gate was changed and new gate required a right and then two lefts. Captain attempted to do it on the left engine... last turn was slightly uphill as well. Jet blast caught an empty cargo container and launched it onto a ramp worker sitting on a tug. Broke damn near every bone in his body.
Less-than-all-engine-taxi is a great idea, until it ain't. And the blame will lie squarely on the captain's shoulders.
