Now that is interesting! Out of all my visits to BHX over the years, I have never seen a go-around! Maybe its the luck of myself 😀
As for the ATC bit, I’ve been fortunate to actually be allowed up into the tower and see how it works and the kind of views it has. There are a minimum of 3 people in the tower at anyone time me thinks, well when I was there anyway.
Maybe they didn’t expect the 737 that landed to exit so slowly?
