Here are two very interesting pictures from the dramatic sinking of U2359 on 2. may 1945. These pictures are from the automatic cameras on the Mosquito fighters from Banff Strike Wing. The pictures are very kind made available for us by Erling Skjold from Norway, who with some complications got them from the intelligence department of the Banff Strike Wing. Thank you very much!

The Mosquitos probably also took some videofootage, but that is nowhere to be found.
One of the pictures has a strange detail on it. If anyone has an idea what this round structure in the air behind the tower is please come forward. According to military experts it does not look like a smoke-ring from the exploding rockets, and it is not a scratch or error on the film either.

Note! The pictures are in a very high resolution, as they are copied from the original film. Each of them has a size of about 20 megabytes.

What is the round structure in the upper left corner?
