Pushback is usually the time when the pushback driver and the crew make explicit comments about the flight attendants aboard the flight. Some pushback drivers require the flight crew to tell a dirty joke before they will disconnect the towbar
Lektros are not bad pieces of machinery, however they do take some practice (not like any other pushback equipment does not need practice...) to get used to because of the reverse steering. The drivewheels are in the front and the steering wheels are in the rear. My trainer compared it to a forklift, and in reality it almost is. After all, it uses similar parts. The only downside to the Lektro is when it is low on battery, it will just die and you can't do anything about it. You will have pushed back a plane partway, and then all of a sudden the thing dies. Not fun. Other than that, they are pretty good machines, especially for pushing back smaller props and RJ's.
