The 732 purchase allowed the Fat Man to pocket yet another hefty commission before pocketing yet another commission for the 733s.
On to less controversial matters: I don't think there'd be a single ex-TAA/Australian Airlines driver who went straight from the Diesel 9 to the 733 who wouldn't say it was a very steep learning curve, particularly since because of a major screwup by Jimmy Bowtie's bean counters, where line training hadn't been included in their plan to introduce the new type.
Someone who was directly involved will correct me if my memory's playing tricks on me, but I think each DC9 pilot completed only four sectors on the 733 before being cleared to the line - agreed upon by the AFAP and the AA pilots on the understanding that there would be a major payback on the part of the company when the next award was agreed upon.
That next award came up in a year all too familiar to many here - 1989... and to say the company did not reward their pilots for the way they (the pilots) helped the company get around the bean counters' screwup might be the understatement of all time.
