Many years ago flew back from Kos to Gatwick. Flight was delayed due to bad weather at Gatwick. As we approached Gatwick, pilot said still very foggy, but was going to try to land. Plane started to drop, then at last minute, abruptly pulled up again. Pilot came on and said 'Well, couldn't see a thing that time, we'll have another go, if that fails we'll have to go to Stansted and bus you back' . On the second attempt you could hear a pin drop, but as we hit the tarmac there was spontaneous applause. Pilots eh?
