Driving
Driving a Douglas Supertug isn't that hard (you have to use the cameras as well). We have two sizes: A smaller version for the RJ's and the regional stuff, and a larger version for everything else.
If you have basic pushing skills, and can spin aircraft from corner gates, you can definitely drive one.
I think that in my travels throughout our system, I think that we are the only hub that we do not push straight back and cut the plane loose. We don't have the real estate to do such, and we have to spin and move the aircraft to a dispatch line for release. All the other airports seem to have enough room to push straight off the gate and release. I wish I have that luxury every day, but I dont. I have learned how to push from corner gates, every gate in my airport from Express to Mainline, you cannot push straight back and release.
Sort of off topic to lighten things up: What aircraft do you think is the hardest to push?
Me personally, I think that the 737-900 is the toughest for me.....
