Minor nit..."Carrying" 400k? Surely you must mean a max t.o. weight?

Yes, the point was the efficiency of the wing. Which for the 767 is
designed to carry 500,000.

I guess they never developed into that weight becsause the 777 came
along

The point was that the wing structure and lift capability are there to
be used in a tanker model.

Typical payloads I see on those stage lengths is about 60-65k for a
767-200.

767-300.
The tanker will (its gonna happen because its an election year) be a
767-200.

The KC-135 was similar to the "short" "707" too. Plenty of room to carry
fuel and was able to lift as much as the large international models.

The MC2 (which may well not get beyond the prototype) will be a -400
So what happens if either a 'bus or Boeing loses DC power? How far
will either likely fly then?

I've not heard of a DC power loss problem. Which airliner has this?
I should have framed the question this way:
How far would either aircraft fly if there is trouble in the E&E bay
that compromises the electrical system and you are down to DC
power...And then you lose even that?


Lets see... 3 AC generators, 2 batteries, 2 T/R's and a HDG. The E&E
bay is accessible in flight. In the airliner, there are lavatories and a
galley above it, yet I've not heard of any trouble.

The KC-135 in the era I'm familiar with could complete it's mission on
battery power alone but it also had 3 AC generators, 1 battery, 2 T/R's
and a HDG.

Please explain your "trouble in the E&E bay" scenario and how you
envision it being handled.
