Outstanding aircraft types that didn't see combat
There must be lots of combat aircraft types over the years that didn't ever get to see action. Of them, which are your favourites?
I'm discounting here the myriad aircraft types that might be considered experimental, odd, lacklustre, humdrum or uninspiring, or were solely involved in non-combat duties (training etc). I'm really looking for examples of mainstream, frontline historic combat aircraft. I'm also discounting types in current air force inventories, on the basis that they might still see combat one day.
So which are your favourites? I had hoped to nominate the English Electric Lightning, but a bit of research shows they were apparently used in a ground-attack role in Saudi Arabia in 1969.
