In researching today’s post; I perceive there is some confusion as to what aircraft type the GE36 first flew on. I believe it was originally tested on the Boeing 727 and later on the DC-9/MD-81 as it is written in the Smithsonian article. Some sources alluded that the DC-9 was the original test aircraft.
