Boeing Model Numbers
I'm new here and struggling a bit to learn how this forum is operated but I would like to correct a statement that I ran across earlier today. The statement that Boeing did not have an official model number 717 is erroneous. After the 367-80 was flown came the contract for a military tanker on which I worked, The model number was 717 and I still have some layouts with that model number in the title block, dated 1954. The 367-80 was actually Model 707 and was given a spurious model number to confuse the competition. The model 717 became the KC -135.
