#OTD 1952 three trains crashed at Harrow and Wealdstone station in Middlesex. 112 people were killed and 340 injured. It remains the worst peacetime rail accident in British history. But I want to talk about Lt Abbie Sweetwine USAF
#HistNursing #BlackHistoryMonth A nurse for 10 years at that point, she was part of 494th Medical Group, some of whose members were on one of the trains. They contacted their base and an emergency response team was sent, all trained in battlefield medicine, which included 7 doctors and 1 nurse, Lt Sweetwine.

Deal agreed for antibody virus tests on NHS. A thread.
OK. Govt says 250k people tested positive. Let's say that's out by a factor of three, and 750k have had the disease. That's 1.12%. So in a random sample of 10k, 112 should test positive, 9888 negative
bbc.co.uk/news/uk-527585… 2/ The Roche antibody test being talked about is said to have a specificity (ability of a test to correctly classify an individual as disease-free) of 99.8% and a sensitivity (ability of a test to correctly classify an individual as ′diseased′) of 100%.

I'd wonder if any journalists will ask #DowningStreetBriefing what the evidence is that Apple Map requests is in any way indicative of *actual journeys taken*? Because without that these are meaningless. From the nots in the dataset
"This data only includes journeys searched for using Apple Maps, and therefore does not include users searching through alternative journey planners."
