This happened as I was leaving, so didn't see/hear it at all (which is odd, as I was in earshot of the tannoy system for ages).
Here are a couple of pics of the 2 aircraft involved, only a short while before the collision.
Is that a pitot tube under the Skyraider's right wing, where it's folded up? If so, that pilot also had to contend with a dead ASI and a missing wing tip. Makes his recovery and landing even better.
So pleased both pilots walked away ok.
