Question for ACAvionics guy?
Why is it that 747s, 767s etc. are coded as 743, 763 etc. in a lot of cases? Is there an obvious reason I haven't clicked into?

The flight schedules only allow for 3-character codes for "Equipment type" used on the flight (prob a throwback to older computer systems). Often the last character is substituded with another to indicate the series or variant of aircraft used. For example "737" is used for the original 737-200 series, while you'll also see things like "738" for a 737-800 series.
"767" usually means 767-200, while "763" would indicate 767-300. "744" is a 747-400 and so on. Same goes for Airbuses, so a "343" is an A340-300.

Kindda a great idea looking back now, but let's look at the evolution of the commercial Boeing airplane.
1st the 707. Then the 727 and the invention of the slat (oh lala), then the 737 with only 2 engines. But then the 747-100 came into play with the 757 comming later. the 767 was developed in part as a smaller wide body and also to fly over all that nasty weather that the rest had to fly through. Now the 777 and the 717 (OK, I don't have an explanation for the 717).
Soon the new Boeing tripple decker, 787!!

Was there not in the Boeing development sequence an earlier 717 (between 707 and 727) that ended up as a pure cargo aircraft? Any info on that? Or am I simply articulating the product of a dream that sought to fill in a numerical sequence?

717(-100) was the original design of the 707 (or 367 as it was originally designated). The fuselage was too narrow (5-abreast) and the airlines got Boeing to widen the fuselage to 6-abreast. The U.S.A.F. C/KC-135s are "717"s.
