I remember reading ATW
about 1982, and at the time, USAir Chairman Ed Colodny when asked about new planes, and he stated that then AL
would be interested in a DC-9 Super 30 as new planes. I guess that AL
wanted an update in the shorter body instead of the -80. If MDD offered the -80 and -87 at the same time, they could've sold a family of airframes as the 737 family. Indeed, AL
chose the 73S and 733, and purchased the 734 when they decided they needed the extra capacity. I wonder if MDD had the -87 available at the beginning, if AL
might have purchased it instead of the F100's if the plane was available earlier on.
