I think they didn’t go around because “out of the window” it didn’t look that far out. Maybe they felt it “a little low”, but well with in the realms of there or there abouts. That’s what this airport does, and that’s why the vast majority of pilots cannot fly a 3 degree profile to touchdown. They will always be low.
On just about every approach I have flown, or I have seen flow (by pilots of much greater talent than me) 50ft call occurs over the sea, 30ft over the beach, 20ft over the threshold. I think this Wizz crew were maybe 10-15ft too low.
Also, only one of the pilots would have undergone any training for this place, and only one of the pilots would be authorised to operate in here. That would be the Captain. It may well have been the first time the FO had ever seen the place, or anything like it.
