It was about the fact it had better payload, better range, better performance and was a better tanking platform which could dispense fuel to more than one aircraft at a time.
Yes, but...the KC10 was
designed as an air refueling tanker.
The TriStar was not.
TriStar was designed as a
passenger aeroplane.
That the RAF mucked it up is
their problem, not Lockheed's.
In the end, of course, the RAF apparently simply does not have the funds to make it work....even in the passenger role.
Hardly suprising.
