This is so much more interesting than it looks, because it's not the nose that sustained damage.
I mean we all know refuelling configuration involve receiver flying behind and below the tanker.
So for top of vertical stabilizer to be hit, the receiver has fly well forward of where it should, basically directly under the tanker, while maintaining close vertical clearance.
And keep in mind these things don't accelerate very fast, at all, it takes quite a bit of deliberate effort and time to advanced until you're directly below the tanker
Or the receiver could have approached the tanker way too fast and yet performed no pitch down as it overshot the tanker, basically violating all approach procedure and don't even have any self preservation instinct
There's a reason this kind of incident has never happened before: it's extremely unlikely.
A missile, on the other hand, usually end up hitting somewhere near the target's tail, just saying.

Also, if both are KC-130, this is how close they have to be flying relative to each other, minimum, for one to clip the top of the other's vertical stabilizer, yeah.
