How many planes apart from tankers were derived from the Boeing 707? I know the 737 and 727 has the same nose but is that the only commonality? Does the 757 share any 707 genes?

The KC-135 and 707 are not the same aircraft. They are closer to the Dash-80 design. After that, your looking at the Boeing 720. Most of the early Boeing's share the same nose design.

As EMBQA says, the KC-135 is not quite the 707, although they're close cousins. Incidentally, the KC-135 (which is a USAF designation) was called Boeing Model 717, which explains the gap between 707 and 727. The designation was purely internal.

707, 727, 737, 757 share the same cabin width, but the fuselages have different cross sections. The KC-135 is a mite narrower.

Shameless plug - For a complete 707 version list: http://www.rosboch.net/aviation.htm#BoeingVersionCodes

Everything that Boeing has ever made  

"707-320-101 320 with enlarged lower lobe 320 with an enlarged lower lobe for passenger seating on a lower deck forward of the wing and more cargo aft of the main gear.
707-520-X Double decker development Double decker with low wings. Length 191'7".
707-520-2X 520-X shrink Double decker with low wings. Shorter than the above.
707-520-X3 Double decker development Double decker with high wings. Length 144'2". Span 142'5". "

Those must have looked veeery interesting! Funny that they were toying with a concept similar to the A380 (4 engined full double decker) that long ago...

Let's not forget to pay homage to the granddaddy of 'em all...the B-47:

Quoting JAM747 (Thread starter): How many planes apart from tankers were derived from the Boeing 707? I know the 737 and 727 has the same nose but is that the only commonality? Does the 757 share any 707 genes

Well let me get a good list started. Remember first of all that the 707 is actually a derivitive aircraft. The 367-80 was the first. The B-47 taught Boeing Engineers a lot about desigining high speed wings but I don't htink I would call it a grandfather.

But anyway here is the list I would start with

367-80
707-100/200/300/400
720
727-100/200 (Upper fuselage lobe)
737-100/200/300/400/500/600/700/800/900/BBJ/BBJ2 (Upper Fuselage lobe)
KC-135A/E/R
C-135
VC-137
CC-137
E-3A/E/F
E-6
E-8
EC-18
T-43 (Upper Lobe)
C-22 (Upper Lobe)
C-40A/B/C (Upper Lobe)
Wedgetail (Upper Lobe)
Phalcon

2H4,


AWESOME pictures!!

You can go a little further than that. All of Boeings airplanes, from the B-367-80 (not counting any MD design) have a common cockpit design. Yes, the cockpits have been updated as avionics and navigation equipment improved, and the Navigator/FE was removed, but it is still basicly the same.

The list includes:
B-367-80
C/KC-135 and derivitives (B-717-100/200)
B-707-100/200/300/400/700 (+ F and all militery derivitives)
B-720
B-727-100/200 + F
B-737 (all derivitives + F + military versions)
B-747-100/200/300/400/E-4/VC-25 + F
B-757-200/300 + F
B-767-200/300/400 (+ F and all military versions)
B-777-200/300 (all versions + F)

Quoting Waterpolodan (Reply 4): Those must have looked veeery interesting! Funny that they were toying with a concept similar to the A380 (4 engined full double decker) that long ago...

Similar indeed, but it would only have had one aisle per deck.

Wish I had drawings of the concepts though...
