Not sure where else to post this, but below is a link to the log of a WWII B17 Navigator.
FYI,
He mentions 'Take Off at xx:xx', and then leaving England 3 or so hours later multiple times. From reading other forums, people think the time may include briefing, preflight, waiting to take off and then getting lined up in the air. B-17 cruise at about 180 mph (I think).
Ashfield is 70 mile NE of London.
