Why do Boeing plane models always start with a 7?
I have seen a very interesting article on Traveller.com written byMichael Gebicki. Please enjoy this interesting article.
Having this said, there is a common question that what happens after Boeing finally rolls out the 797?
Aircraft types are known by a kind of shorthand every flyer knows. Tell anyone your next trip is aboard an A380 or a 747 and they should know what you're talking about, but is there any rhyme or reason for the way aircraft manufacturers name their aircraft? Why does every Boeing you've ever sat in probably start and end with the number 7? And why do Airbus models always seem to start with a 3?
But Boeings didn't always start with the number 7. Some early aircraft were known as the Model 40, Model 80, Model 247 and the glorious pre-World War II Boeing Model 307 Stratoliner, the first commercial aircraft with a pressurised cabin. Even the heavy bombers that Boeing built for the US military during the war were originally designated the same way. The B-17 Flying Fortress was Model 299 while the B-24 Liberator was known within Boeing as Model 32.

So why was the first Boeing jet aircraft known as the 707 rather than
the 700 when it first took to the air in the 1950s? Because Boeing's
marketing department intervened, and just as 007 sounds better than
plain old 7, 707 sounds better than 700. So taken was Boeing with the
number 7 that the company has stuck with it ever since, starting and
ending each of its jet aircraft type with that number, a corporate lucky
charm.
Since that time it's been a steady progression for Boeing aircraft, from the 727 of the 1960s right up to the 787 Dreamliner, although the airline skipped a beat with the narrow-bodied, short-range 717, which only entered commercial service in 1999, well after Boeing's 777.
Each of those models is further broken down into sub categories with a dash commonly used to separate the successive designs. Early-model Boeing 707s were designated the 707-120, followed by the shortened, longer-range 707-138, the stretched 707-320 and a short-range, smaller iteration, the 707-720, among several others.

Boeing and the magic number seven
In
the postwar period Boeing shuffled the deck and reclassified its
aircraft, giving each category three-digit numbers. A 300 or 400 number
denoted a propeller-driven aircraft, 500 was for turbine-powered
aircraft, 600 for rockets and missile products and 700 for jet aircraft.
