Robmack, there are three B-17 pics on the page - one, as you point out is John Crewdson getting intimate with Bovingdon while filming "The War Lover", another colour shot which is between the Vulcan and Lancaster pics is Don Bullock scattering the hay at Barton.
By the way, if you can get a copy, read "Everything but the Flak" by Martin Caidin, all about getting the War Lover B-17s across the pond.
