Calling The Dash-80 A "707"

The Boeing "367-80" was the famous prototype for the 707/720 mainly civil transport and for the 717/739 (KC-135) military transport/tanker. The thing that confuses me is that "Boeing 707" was written on its tail at one point (and it still has this in the Smithsonian museum), so I'm wondering, was this just for marketing purposes? I don't think it's correct to consider it a real 707 because it was a rough developmental airplane for both the 707/720 and the 717/739, with different upper fuselage lobe widths than the 707, and not included in the line numbers of the 707. Is there therefore any logic other than sentimentality in including the 367-80 with the 707, if the KC-135 is not? (I'm asking because some people do it and I think it's incorrect).

While similar, you're right, they are two different airplanes, and I believe it was done only for market purposes. The 367-80 is decidedly not a 707.

I personally have noticed this too and have come to the conclusion that if you remember the 367-80 was barrel-rolled over Lake Washington and it was heard around the world. So for all intents and purposes it may have been something for marketing in saying, "Look, when you buy a 707 you are buying a strong, reliable aircraft that the people have come to know and love".

Maybe its size.The dash 80 is surrounded by other priceless aircraft and they have to fit into the hanger at dulles.Ive been there twice and the dash 80 looks quite small-maybe the prototype was the only type small enough for the museum?

BTW,i would LOVE to see if airbus tries to barrel-roll their A380 Big grin  Big thumbs up

As noted above, you can barely call the Dash 80 even a prototype as it is so different than the 707. You would be surprised at how much of it was "hand made" and parts made of wood!

For those who don't know (like myself), what are the major differences between the Dash 80 and the B-707?

The KC-135 is wider than the -80 and the 707 is wider than the KC-135.

The -80 was basicly a concept airplane and it served Boeing very well.

EA,
The main differences are in the length and width of the aircraft, but I believe that there are also some internal changes along with that as well as different manufacturing processes.

The reason why the 707 prototype was called the Dash 80 was the fact to preserve secrecy during prototype construction, Boeing designated the prototype 367-80, 367 essentially being a model number for the Stratocruiser.

Mind you, it was going to be called Boeing 707 when the plane's registration number was N70700.  Smile
