Eileen Nearne, Wartime Spy, Dies at 89

The Grand Slam was a 22,000 lb (10,000 kg) earthquake bomb used by RAF Bomber Command against strategic targets during the Second World War. Known officially as the Bomb, Medium Capacity, 22,000 lb, it was a scaled up version of the Tallboy bomb and closer to the original size that the bomb inventor Barnes Wallis had envisioned when he first developed his earthquake bomb idea.

No information on this picture, perhaps of Battle of Britain. We have two alternatives to the caption:
1. A Spitfire about to give the “coup de grâce” for its prey, an He 111.
2. A Spitfire respectfully waiting for its wounded prey (a He 111) to give the fatal plunge down into the sea.
