-80
Mr. Ried UK. Since I worked on the 367-80 I feel that I might have some knowledge about it. The Boeing model number was 707 and the prototype had that designation pasted all over the exterior. If the -80 wasn't model 707, what was it?
The I wish that I could print the some of the drawings that I have to show the progressive changes in the configuration of the 367-80 to the 717 and the 717 to the production version of the 707. The biggest change was the increased diameter in the upper lobe of the 707 to accommodate more seats abreast to compete with the DC-8 . The planform of the -80 is almost identical to the 707 but slightly smaller. The structural centerlines are identical as is the wing sweep. The -80 fuselage is slab sided where the 717 upper lobe is semi-circular, the 707 upper lobe is a larger circle that produced a crease line that does not exist on the -80 or 717. The 717 (KC-135) weighed 248,000 pounds and the 707 was something like 224,000 but the planforms were identical.
The recent "717" was a marketing gimmick, the originators paying no heed to the existence of one 717 already on the books.
