I know the 707 is a old jet, but I really like them. When I was a child, I asked my father why there was not that many 707 flying, and he told me the the 747 replaced them. I remember watching the movie Airport and I just hearing those JT3-D start up and spool up for taxi was one of my favorite part of the movie. The I believe the 707 was the second aircraft to use JT3-D ( TF-33) and they have B-52H style engine cowl. If it was not for the 707 the 727, 737 and 747 would not have been built. Also the 707 was the first jetliner build by the company who built the Statocrusier. If you like 737 and BAe-146/RJ-100-80, how could not like 707 it is a mixer of both, because look's a stretch 737 body with four engines. These are the reason like about these these old jets.
What are yours?
: In another post some body said the 707 looked like a flying Audrey Hepburn, I would really like to hear from him.
