taken.

Perhaps it was Richard H. O'Kane? In one of his books, O'Kane wrote of a
navigational emergency that happened when he was an XO (executive
officer, 2nd in command) during a war patrol. On U.S. subs in WW2, the
XO was also the navigator. It was the practice on his vessel to tear out
and discard the old daily pages in the almanac. But one of his
quartermasters made a terrible mistake. He threw away a few pages before
their time. They went overboard in the garbage.

The two men worked secretly for hours in the sub's tiny office,
reconstructing the missing tables with the help of a slide rule. After a
few days they were back on the almanac with no trouble. The captain
never found out about this.
