WI the DC-10 had never been approved?

This is a possible sales list for the VC-7. It is a combination of:
  1. OTL VC10 Customers
  2. OTL Convair 880 and 990 Customers
  3. OTL Boeing 707 customers that also bought the Convair 880 and 990 and/or the VC10
  4. OTL Douglas DC-8 customers that also bought the Convair 880 and 990 and/or the VC10
  5. OTL Boeing 707-420 customers (i.e. the Conway powered version)
  6. OTL Douglas DC-8-40 customers (i.e. the Conway powered version)
  7. Quantas and Air New Zealand

Are there any Convair products that the British would want to buy? There would be no CV-880 and CV-990 ITTL. Hopefully the 102 OTL aircraft of that family would be substituted by 102 Convair built VC-7s sold to the same customers.

All I can think of is the F-111, which they bought (and then cancelled) anyway after the TSR2 was cancelled. ITTL with Boeing loosing a substantial amount of civil work to Convair/GD I think there is a good chance that the TFX contact would be awarded to Boeing instead of GD.

I was continuing my initial alteration in which Boeing has folded long ago, likely as a result of no new long-range bomber after the B-17/B-24 or Consolidated tapped to build it versus Boeing or some other series of calamities. In my no WW2 timeline the B-29 is rather lightly penciled and subject to never happening, Boeing does not get German aerodynamic research and if it builds a B-47 it is as disappointing as the B-45 or whatever else the USA was building without swept wings, engine pods and other Wonder Weapon gimmicks. You are free to ignore all that. But if Consolidated had built the follow-on to B-24 then it could go on to the B-36 and become TTL's Boeing. Boeing here retreating back into flying boats or more defense oriented projects as it exits commercial jet airliners, akin to how Convair itself failed to get into the running.

Boeing does not get German aerodynamic research
I wanted to single this point out. Germany was by no means the only country researching swept wings. Curtis Wright built and flew a fighter (the XP-55) with a swept wing in 1943, long before the US got it hands on German data. So using as a POD that "Boeing does not get it's hand on German aerodynamic research" is not going to kill Boeing. IIRC, Boeing was already toying with the idea of a Swept Wing for the B-47, but hadn't committed to it. The data just helped them make the final decision.
 
Curtiss XP-55 Ascender’s swept wing is not relevant to jet airliner design. Curtiss designed it before anyone understood compressability at high Mach numbers.
Instead, XP-55 got swept Wings to hold vertical stabilizers far enough aft that they could contribute to yaw stability.
The second reason for sweeping wings is to adjust the centre of lift to (almost) match the centre of gravity. Swept wings allowed the (heavy) engine far enough forward to balance the airplane.
This is the same reason why most of Burt Rutan’s small canards (Varieze, Long Eze, Defiant, etc.) have swept main (rear) Wings.

I'm aware the reasons were different. My point was that the Germans weren't the only ones researching swept wings and that manufactures like Boeing would have developed them anyway.
