Every time I read that Sled tale above, it makes me smile!
Much like the (almost certainly apocryphal) tale Of the US and their U2 over Westminster....Story runs as follows;
USAF feel awfully chuffed that they've sneaked over the UK at high altitude and taken a photo of the Houses of Parliament without being detected.
USAF send said photo to MOD, with a slightly gloating tone
MOD reply, "Thanks chaps. Very interesting. However, we think this is far more interesting", enclosing a photo taken from above, of the same U2 over Westminster
