Let's hope that such overworked ground folks don't walk into a PROPELLER. As deadly as a guillotine during the French Revolution.
This killed a young lady working under a Metroliner in Newark (EWR) a few years ago, and to another lady in Memphis (MEM), where she walked into a Saab 340 prop: both might have involved unplugging external power cords. These tragedies might have happened at night, but props are invisible in the daytime, too.
Are they carefully trained to always walk well clear of the engines, with no exceptions allowed? Or are they always in a hurry, with on time departures most important?
