So, what would you pilots do in the horrible event that 4/. materialised in front of you?
I'd probably land. And I might even do the do the same (again) if I didn't get a clearance because the Tower couldn't get a word in edgeways. The last time I did that I received, presumably for the benefit of a tape somewhere, an "ABC 123, just to confirm you were cleared to land" which I though was pretty good.
