The Squalus

May 23, 1939. A new submarine, on a test dive off the Isles of Shoals, New Hampshire. She sank, with fifty-nine men aboard.

Twenty-six drowned. Thirty-three were brought up in the McCann Rescue Chamber, which had never been used in a real rescue. The chamber went down on its cable with men from the rescue ship Falcon in it. It sealed to a hatch. It came up with the sub's men. It went down again.

The sub was raised that September. She went back to sea the next spring under a new name, the Sailfish.

In the margin of the Log, in pencil, beside both names: SS-192. The pencil is soft, and it comes off on your thumb.
