Great Dane - RDAF F-91 Thunderceptor

Odd operator choice, bit it looks very good. 

Not really. As stated, they were already operators of the F and G, and then they were 'persuaded' lol

Yes, but the F-91 was a highly specialized and complex interceptor, while the F and G were rather fighter bombers. I meant it from that point of view.

The choice of operator is a valid question. Basically, I thought the XF-91 would look good in overall green.

That meant either Canada or Denmark. I felt the XF-91's short range would not suit Canada's air defence needs, but Denmark could usefully use the aircraft to intercept Soviet bombers over the Baltic.

Not much more complex than an F-86D, which a number of NATO countries operated, and who were flying F-104s only a few years later.

The rocket engines made the F-91 a whole order more complex than any of the 'normal' jets of the period though.

Just that. Concerning radar or weapon technology the F-91 was not better than the F-86D. But it was a much more complex aircraft concerning mechanics and propulsion, esp. the rocket engines require their own infrastructure.

And it does

It highlights the conglomeration of weirdness.

I've been trying to decide what I think of this aircraft & have come to the conclusion that it's "Quirky Cool".

Having read up a bit on RDAF experiences with the F-86D, of which they had two sqns, they did struggle a bit to keep them in the air. As stated, they were a bit more complicated that the straight-wing F-84's the Danes flew simultaneously. The two main field of worry was the electronics that didn't cope too well with the humid northwest european climate, and the fuel system of the afterburning jet engine, the afterburner adding a further layer of possibilities for malfunctions and leakages.
Given this, I think Thomas's concerns are valid as such, but then again - the Danes did operate the F-86D and then within a few years, the F-104G with no further problems than any other European operator, so why not the F-91?

I further suspect our dear @mat being the resident RDAF specialist, might have some further experiences to share, should we poke him enough.
