Nose wheel collapse is something that pilots practice on simulators all the time. In my opinion (obviously I don’t know all the facts) the pilot here obviously knew there was a nose wheel fault and circled to burn off fuel and then landed at an airport with a long runway with plenty of distance to make a careful emergency landing. Probably keeping the nose wheel up as long as possible. Only putting it down when the plane had slowed down to a point where there was no lift left. It looks to have been a text book safe emergency landing. Well done pilots!
I landed at Leeds Bradford in the 1980s on a Fokker Friendship which also experienced nose wheel collapse. That I think was unexpected for the pilots because we had no forewarning. The plane lurched forward very suddenly when it happened. The pilot obviously then braked severely, far harder than you normally experience, and we stopped on the runway, with all engines immediately shut down. There was then a short gap whilst (I think) the crew decided whether to evacuate the passengers on to the runway, or just to sit tight till the emergency services came. In the event we sat tight. The only injury on board was from someone hit on the head by flying hand luggage. When the plane stopped, all the over-head lockers burst open, and a lot of the hand luggage up there shot out, and became missiles. Bear that in mind the next time you see someone stick a 40 KG piece of hand luggage in the locker above your head.
