"The RC-135s have absolutely nothing in common with the E-3Ds. The E-3s are an entirely different aircraft. The fuselage is different the wings are different. What do you not understand about DIFFERENT?"
Exactly my point - one of the E-3Ds has the wrong wings on!! It may be that they are 135 type wings and from an E-8 or similar, but they are the wrong wings which do not have the correct wiring runs etc! It is presumed that there was a set of "spare" wings in the factory and they were used up rather than building a new set. I know that this seems far fetched, but it is correct!
