The thing I look out for is how they offset the "powerpush" behind the aircraft after start. And then they don't bring it in until the aircraft is powering away. Assuming something similar to Waldo's experience(bay18 to F intersection) it could get close if the guy with the remote pushed the controls the wrong way.
Whenever I see the guy with the remote standing out on the tarmac I have to smile and just shake my head at how amazing things are in the industry. I mean try telling someone 15 years ago that the 'young kid with the remote control car over there' will be doing that for a living only with moving aircraft. It really looks like a big kid having serious fun.
