Once upon a time the Navy took this photo:
Apparently the original caption read:
Skate (SSN-578), surfaced at the North Pole, 17 March 1959
But it seems to have morphed to:
Skate (SSN-578),taken in summer, perhaps in August 1958.
The above is from Real-Science: Navy Changes Their Caption
Innocent error by some alarmist file keeper who couldn’t conceive of the upper caption being correct?
An adjustment to better suit the Global Warming hysteria meme?
