The book is an excellent documentary of the industry but there is a big error in it - when the 1985 UAL pilot strike is mentioned (pg. 264), it says that there was a "corps of strikebreaking pilots, some 570 strong" in training, The class of 570 as they are known was NOT hired as strike replacements and they honored the strike at the risk of their jobs. In a later judgement, it was ruled that UAL had to honor their job offers to these pilots and retro pay was finally awarded. This group wears a pin with the number 570 on it to indicate their solidarity during the strike and with the striking pilots.
