Airmanship
Nearly happened at ZRH with two DC9s flying cloud break ils14 left hand circling 28.
lead aircraft had a mate in the rhs who suddenly lost daylight through his eyebrow window..belly of number two. All well below 500ft on short final.
Number 2 was being flown by a swede whose abilities didnt match his ego.
Tower had a trainee.
Mate grabbed stick and stuffed it forward.
Supervisor made some sort of panic call SRxxx confirm number 2..who went around.
saved a couple hundred lives and a big whole in Kloten.
Later flew with Swede on DC10 and threatened to refuse to fly with him again.
lucky to survive his career.
