Wow, you guys came up with a lot of things I never knew or had
forgotten. Great responses. If we open the criteria to "Combat
aircraft that have not seen combat - in any configuration, with combat
being defined as projecting force to affect the outcome of some
conflict", then there aren't very many that didn't get a chance to do
what they were built for - and their crews trained for.

A bit sobering, actually.

And recce is still a bit squishy - does the EP-3 "victory" over the
F-8 (I think that is what it was) count as "combat"? That sure would
surprise a lot of people!

Just one question:

What is a "Squark"?
