Eric,So, my original comment stands -- speed is an issue, almost as much as the inferior equipment.
The tractor clearly shouldn't be going 15 mph if it either can't stop, or stops so hard that people get hurt.
And no, I don't buy the argument of the company or the airport forcing you to go fast.
Come on, you can't for a second believe that you can get a 777 across a 150' wide runway with the tail cleared for the landing plane, which often times was on a 2--2 1/2 mile final, or less than 2 minutes out, without giving it everything you got. Then comes the hard part, trying to get it to stop in less than 200', before the next runway. This of course doesn't even take into account the inclines and declines on the runways and taxiways for water runoff, which makes it even harder. If I took your advice, I'd either be dead from an accident or fired for refusing to do my job.
