An update on the whole Millwall thing. Well, a teaser, anyway. I've had an email from Chris Going letting me know how his research into the Luftwaffe's photoreconnaissance flights over Britain on the first day of the Blitz, 7 September 1940. Can't say too much, but he did authorise me to say that 'interesting things are in store', and to post one of the photographs taken that day.
Just as with that iconic Blitz image, there are other aircraft in the frame (in the lower right quadrant). These aren't Heinkels, though. Are those wings elliptical?
