Photographs taken by the first responders appeared to show at least one of the prime pump switches in the off position. When examined by the AAIB after the accident site had been stabilised, both the No 1 and No 2 prime pump switches were found to be in the on position.
Since there is no shortage of people willing to chip in with theories about why things were or were not done or seen, who wants to have a go at explaining why the AAIB think it relevant to include the word appeared?
Perhaps it is because the photo is not clear enough to say, one way or another. Some posters seem to ignore facts, and have distorted the report to fit their theory.
