I can think of two off the top, N7265U, a
UA 727-222 , and N746US, an Ex-ANA 727-281 that flew with US for a while, the only picture I was able to find of N746US showed her in storage, but there seem to be no pictures of her in operation with US. A third one that came to me was N171AW, my very first 737-200. There are no pictures of that plane in
HP colors, only in the colors of her delivery customer, TACA I think and alot of pictures in the liveries of the various airlines that came after TACA, but none in
HP colors. A fourth is N721RW, a 727-2M7, again, no pictures of her in
NW paint, the airline i flew on, just Hughes Air West, Republic, and the paint of the cargo carrier she flew for after being retired from
NW. The fifth and last is N926RM, A DHC-7. The only pictures I could find of that one were ones of her being scrapped, none of her in service wearing the
CO meatball colors she was in when I flew on her.
