I imagine it was a bit more... hysterical in the world of 28DL.Well it looks like the UK is effectively being quarantined by the international community over the new Covid strain spreading rapidly thorough London and south east England. The Netherlands and Belgium have banned all travel from the UK and it seems France is about to do the same .
There was also somewhat chaotic scenes last night as thousands of people rushed to get the last trains out of London before the city enters Tier 4 restrictions. I could imagine the London train stations might have looked a bit like this during the timeline I've written.
Like those accounts of German soldiers trying to cling to the last planes out of Stalingrad hysterical.
