My favorite 570 story is this:

Sometime in January or Feb of 2000, before the summer from hell, a crew was flying with one of these DB's from MIA to Santiago. He was on his own mission from God to stick it to the company. They flew across the Amazon at .68 Mach, they were assigned .80. The two FO's pretty much begged him to speed it up to .80. He refused. It is a non-radar environment, and they were supposed to be using "Mach number technique".

They landed in Santiago, and had a very long taxi back. They taxied back at 2-3 knots, for almost an hour. A half a dozen other aircraft landed after them, and were stuck behind them. A Lufthansa 400 was directly behind them. They screamed over and over to have ground get United out of their way.

Later, when the crew got to the hotel, the Lufthansa crew checked in right after the United crew. Apparently the Lufthansa crew was not amused, and confronted the United crew.

True Story.

Take a scab, and add arrogance, and an entitled attitude, and you have a 570. Yeah, there are some decent ones, but in my extremely extensive experience flying with both them and scabs, I stand by my statement. They have earned it.
