Arriving London - windy!

Very lively landing as a lot of wind and I was sitting in the last row.
In the extra - leaving Geneva.

Re Covid Heathrow precautions: we were told in Geneva airport we would have to fill out a certain form on-line for the UK authorities or risk a £100 fine. I did but on arriving at Heathrow no one asked to see it - I just went straight through to passport control. Not quite sure how this works.
