Submarine wakes
I deleted that deliberately, because I realized I was relating a (rumor?) I had heard during my spook days, and I was not certain as to its correctness, or, if it was correct, whether or not it might still be classified.
But I thought I had gone into the trash folder and deleted it there, too. Apparently not, or perhaps some one saw it in the interval between posting and deletion (it couldn't have been more than a few minutes).
If anyone reads this msg, pls acknowledge.
