Many airlines do not employ staff to handle cargo on the ground, that is why handling agents remain in business?
For every, perhaps, 4 flight crew jobs there will be 1 loadmaster job and every handling agent loader on the planet, it seems, dreams to be aircrew thus airlines get swamped with applications from wannabee loadmasters!
There has to be an easier way to earn a living than flying thru darkest Africa in the dead of night trying to prevent ground staff from nicking the skydrol or indeed the wheels!
