Third in a series of seven photographs showing the rescue dramatic air-sea rescue of Ensign E.H. Barry, USN, pilot of a Grumman AF Guardian when he was forced to ditch his plane immediately after taking off from the aircraft carrier USS Block Island (CVE-106). The series was taken by a Navy photographer on the bridge of the USS Bearss (DD 654). During the rescue, the pilots parachute opened, making it impossible for the helicopter to complete the rescue and pull him from the helicopter sling. After hitting the water for the second time, Ens. Barry began cutting his parachute shroud lines. Before he had completed cutting them, a motor whaleboat from the USS Bearss (DD-654) rescued him from the sea. Approximately twelve minutes after he crashed, Ensign Barry was on board the USS Bearss (DD-654) and being treated for minor cuts and abrasions. In this third photograph, all the slack has been taken out of the shroud lines to the parachute and the strain is increasing on the pilot until the point is reached that he must release the helicopter sling.

Approximately twelve minutes after he crashed, Ensign Barry was on board the USS Bearss (DD-654) and being treated for minor cuts and abrasions. In this photograph, the pilot is hanging from the helicopter sling with the parachute shrouds trailing in the sea. Just prior to the time this photograph was taken, the pilot had pushed back the canopy of the plane and swam under water a short distance from the plane before coming to the surface. A wing tank is shown floating between the helicopter and the plane. At this time the shroud lines of the parachute are relatively slack.

The Trieste descended 35,797 feet into the Challenger Deep—setting a record that was not broken until April 2019, when Victor Vescovo’s Limiting Factor submersible dove to 35,843 feet

The US Navy attack submarine USS Annapolis (SSN 760) rests in the Arctic Ocean after surfacing through three feet of ice during Ice Exercise 2009 on March 21, 2009. The two-week training exercise, which is used to test submarine operability and war-fighting capability in Arctic conditions, also involved the USS Helena (SSN 725), the University of Washington and personnel from the Navy Arctic Submarine Laboratory.

Three polar bears approach the starboard bow of the Los Angeles-class fast attack submarine USS Honolulu (SSN 718) while surfaced 280 miles from the North Pole. Sighted by a lookout from the bridge (sail) of the submarine, the bears investigated the boat for almost 2 hours before leaving. Commanded by Cmdr. Charles Harris, USS Honolulu while conducting otherwise classified operations in the Arctic, collected scientific data and water samples for U.S. and Canadian Universities as part of an agreement with the Arctic Submarine Laboratory (ASL) and the National Science Foundation (NSF). USS Honolulu was the 24th Los Angeles-class submarine, and the first original design in her class to visit the North Pole region. Honolulu was assigned to Commander Submarine Pacific, Submarine Squadron Three, Pearl Harbor, Hawaii.
