The only people who knew if there was thick fog on the approach/ threshold are the pilots on this approach. On the ground you can be in thick fog and then 10m later be in a clear patch. So please can all the non commercial pilots please stop saying it was a gin clear day. At the time and place the jet landed, the only people who knew the weather at that specific point of the airport would have been the pilots.
And yes, I am a pilot, thousands of hours on jets and yes, LVO qualified.
