USS Macon (ZRS-5)

Macon was christened on 11 March 1933, by Jeanette Whitton Moffett, wife of Rear Admiral William A. Moffett, Chief of the U.S. Navy's Bureau of Aeronautics.[7] The airship was named after the city of Macon, Georgia, which was the largest city in the Congressional district of Carl Vinson, then the chairman of the U.S. House of Representatives' Committee on Naval Affairs.[6]

The airship first flew on 21 April, aloft over northern Ohio for nearly 13 hours with 105 aboard,[8] just over a fortnight after the loss of Akron in which Admiral Moffett and 72 others were killed. Macon was commissioned into the U.S. Navy on 23 June 1933, with Commander Alger H. Dresel in command.

On 24 June 1933, Macon left Goodyear's field for Naval Air Station (NAS) Lakehurst, New Jersey, where the new airship was based for the summer while undergoing a series of training flights.[9]

Macon had a far more productive career than Akron, which crashed on 4 April 1933. The commanders of Macon developed the doctrine and techniques of using her on-board aircraft for scouting while the airship remained out of sight of the opposing forces during exercises.[10] Macon participated in several fleet exercises, though the men who framed and conducted the exercises lacked an understanding of the airship's capabilities and weaknesses.[11] It became standard practice to remove the landing gear of the Sparrowhawks while aboard the airship and then replace it with a fuel tank, thus giving the aircraft 30 percent more range.[12]

While on a long duration flight over the Pacific, Macon was able to locate and track the cruiser Houston, which was carrying President Roosevelt on a trip from Hawaii to Washington.

Macon first operated aircraft on 6 July 1933 during trial flights out of Lakehurst, New Jersey. The planes were stored in bays inside the hull and were launched and retrieved using a trapeze.[13]

The airship left the East Coast on 12 October 1933, on a transcontinental flight to her new permanent homebase at NAS Sunnyvale (now Moffett Federal Airfield) near San Francisco in Santa Clara County, California.[14]

In 1934, two two-seat Waco UBF XJW-1 biplanes equipped with skyhooks were delivered to USS Macon.

In June 1934, Lieutenant Commander Herbert V. Wiley took command of the airship, and shortly afterwards he surprised President Roosevelt (and the Navy) when Macon searched for and located the heavy cruiser Houston, which was then carrying the president back from a trip to Hawaii. Newspapers were dropped to the President on the ship, and the following communications were sent back to the airship: "from Houston: 1519 The President compliments you and your planes on your fine performance and excellent navigation 1210 and 1519 Well Done and thank you for the papers the President 1245." The commander of the Fleet, Admiral Joseph M. Reeves, was upset about the matter: but the Commander of the Bureau of Aviation, Admiral Ernest J. King[15] was not. Wiley, one of only three survivors of the crash of the Akron, was soon promoted to commander, served as the captain of the battleship West Virginia in the final two years of World War II, and then retired from the Navy in 1947 as a rear admiral.

Macon over Moffett Field

On 20 April 1934,[16] the Macon left Sunnyvale for a challenging cross continent flight east to Opa-locka, Florida. As with the Akron in 1932, Macon had to fly at or above pressure height when crossing the mountains, especially over Dragoon Pass at an elevation of 4,629 ft (1,411 m). Then, in the West Texas heat, the sun raised the helium temperature, and the consequent expanding gas was automatically venting as the airship flew along at pressure height once again. Full engine power was required as the weather became turbulent. Following a severe gust near Van Horn, Texas, a diagonal girder in frame 17.5, near the fin junction, failed, followed soon by a second diagonal girder. Rapid damage control, led by Chief Boatswain's Mate Robert J. Davis, repaired the girders within a half hour. Macon completed the rest of the journey safely, mooring at Opa-locka on 22 April. More permanent repairs there took 9 days. However, the addition of duralumin channels, to reinforce frame 17.5 at its junction with the upper fin, was not completed. Grounding the Macon, until these reinforcements were made, was considered unnecessary.[17]

On 12 February 1935, the repair process was still incomplete when, returning to Sunnyvale from fleet maneuvers, Macon ran into a storm off Point Sur, California. During the storm, the ship was caught in a wind shear which caused structural failure of the unstrengthened ring (17.5) to which the upper tailfin was attached. The fin failed to the side and was carried away. Pieces of structure punctured the rear gas cells and caused gas leakage. The commander, acting rapidly and on fragmentary information, ordered an immediate and massive discharge of ballast. Control was lost and, tail heavy and with engines running full speed ahead, Macon rose past the pressure height of 2,800 ft (850 m), and kept rising until enough helium was vented to cancel the lift, reaching an altitude of 4,850 ft (1,480 m).[18] The last SOS call from Commander Wiley stated "Will abandon ship as soon as we land on the water somewhere 20 miles off of Pt. Sur, probably 10 miles at sea."[19] It took 20 minutes to descend and, settling gently into the sea, Macon sank off Monterey Bay. Only two crew members were lost thanks to the warm conditions and the introduction of life jackets and inflatable rafts after the Akron tragedy.[20][21][22] Radioman 1st Class Ernest Edwin Dailey jumped ship while still too high above the ocean surface to survive the fall and Mess Attendant 1st Class Florentino Edquiba drowned while swimming back into the wreckage to try to retrieve personal belongings. An officer was rescued when Commander Wiley swam to his aid, an action for which he was later decorated.[23] Sixty-four survivors were picked up by the cruiser Richmond, the cruiser Concord took 11 aboard and the cruiser Cincinnati saved six.[19]

Eyewitness Dorsey A. Pulliam, serving aboard USS Colorado, wrote about the crash in a letter dated 13 February 1935:[24]

Tuesday it was so rough, and with the rain, we had an awful time getting along. We had gunnery drill Tuesday and more fleet maneuvers. The Macon came out about 1 pm Tues. to maneuver with the fleet and to enter Frisco with us this morning. The Macon came out in the storm not knowing that she would never get back to land. The Macon circled high above the fleet all the afternoon, and about 6 o'clock, radio messages began coming in that the Macon had had casualties and would have to land. The C.C. of the fleet radioed all ships in company with us to go at full speed for the wreckage. The crew abandoned it as soon as it hit the water, and all were saved except two. There were 83 men in the crew. The wreckage sank within a few minutes after it hit the water. We lingered around the spot where it sank looking for any parts which might be floating around. The search lights on all ships were combing the waters all through the night. The crew to the Macon were floating around in rubber floats and almost froze to death. I had to read about the Akron disaster, but this one I witnessed. The commander Clay had just been transferred to the Macon from this ship. This may contradict with the papers, but this is straight. There was an explosion in the tail and they could not control it.

In another letter, dated 16 February 1935, he wrote:[24]

I guess that you all read all about the wreck of the Macon. Well, the papers out here were full. I guess the Navy sunk about 3 million dollars there in about 20 minutes. The people will have to pay that back in taxes. It sure was a pity that the Macon had to sink. It sure was pretty sailing around when the sun was shining on it. There sure was plenty excitement on board here that night. Everybody was trying to see what had happened. When the thing hit the water, the gas caught on fire and burned almost all night on the surface of the water after the bulk of the wreckage had sank. The Macon was supposed to go to Hawaii in May. They had started fixing up a field for it.

Macon, after 50 flights since it was commissioned, was stricken from the Navy list on 26 February 1935. Subsequent airships for Navy use were of a nonrigid design.

A depiction of the crash by artist Noel Sickles was the first piece of art sent over the wire by the Associated Press.[25]

A more complete return, including exploration with remotely operated vehicles and involving researchers from MBARI, Stanford University, and the National Oceanic and Atmospheric Administration's Office of National Marine Sanctuaries, took place in September 2006.[27][28] Video clips of the expedition were made available to the public through the OceansLive Web Portal, a service of NOAA.

The 2006 expedition was a success, and revealed a number of new surprises and changes since the last visit, ~15 years previously. High-definition video and more than 10,000 new images were captured, which were assembled into a navigation-grade photomosaic of the wreck.[29]

The location of the wreck site remains secret and is within the Monterey Bay National Marine Sanctuary. It is not accessible to divers due to depth (1,500 ft or 460 m).[30][33][34]

The U.S. National Park Service states:[35]

When the USS Macon was christened on 11 March 1933, the rigid airship was the most sophisticated of the Navy's lighter-than-air (LTA) fleet. The Macon exhibited the highest expression of naval LTA technology during the ship's short career. At 785 feet in length, the airship's size captured American fascination during flyovers of U.S. communities as chronicled in numerous advertisements, articles, and newsreels. The dramatic loss of the Macon and sister ship Akron within two years of each other contributed to the cancellation of the Navy's rigid airship program. The archeological remains of the USS Macon lie off California's Big Sur coast in NOAA's Monterey Bay National Marine Sanctuary. The site also contains the remains of four of the airship's squadron of small Curtiss F9C Sparrowhawk scout aircraft which the Macon carried in an internal hangar bay.

The site was listed on the U.S. National Register of Historic Places on 29 January 2010.[32] The listing was announced as the featured listing in the National Park Service's weekly list of 12 February 2010.[36]
