So- can anyone explain why there are a few 742 out there (Polar Air Cargo to name one) with JT9Ds that dont look like any other the other JT9Ds on 747s?? What I mean is, they look like the JT9D when used on the DC-10-40 or Airbus A300, they dont have that same look as UAs 742, NW 742s or any other ones I can find!
Whats the reason for the different cowlings and intakes?
