NC-4

NC-4. The NC-4 was a Curtiss NC flying boat, one of four built for the United States Navy following World War I. It achieved lasting fame in May 1919 by completing the first transatlantic flight, a historic journey staged via the Azores and Lisbon to Plymouth, England. Though not a non-stop crossing, its successful navigation of the treacherous North Atlantic demonstrated the potential of long-distance flight and marked a pivotal moment in aviation history.

Design and construction

The NC flying boats originated from a wartime requirement by the United States Navy for an anti-submarine warfare aircraft capable of crossing the Atlantic Ocean under its own power. Led by Glenn Curtiss, the design team at the Curtiss Aeroplane and Motor Company created a large, triple-engine biplane flying boat with a wooden hull. The initial design, the NC-1, was developed with significant input from the Naval Aircraft Factory in Philadelphia. The NC-4 was the fourth and final aircraft of this series, constructed at the Curtiss plant in Garden City, New York. It was powered by three Liberty L-12 engines and featured a crew compartment for five, including positions for pilots, a flight engineer, a radio operator, and a navigator. The design emphasized ruggedness and overwater navigation capability, incorporating advanced (for the era) radio equipment and navigation instruments.

First transatlantic flight

The transatlantic attempt was organized by the United States Navy to demonstrate American aeronautical prowess. A squadron of four NC boats—NC-1, NC-2 (used for parts), NC-3, and NC-4—departed from Rockaway Beach, New York, on 8 May 1919, commanded by John H. Towers. Their route relied on a chain of United States Navy destroyers stationed across the Atlantic Ocean as navigational markers and rescue vessels. After a stop in Halifax, and Trepassey, the flight headed for the Azores. Encountering heavy fog, NC-1 and NC-3 were forced down onto the ocean; NC-1 was scuttled after its crew was rescued by the Greek freighter SS *Ionia*, while NC-3 drifted for days before reaching the Azores under its own power. Only NC-4, commanded by Albert Cushing Read, successfully reached Horta on 17 May, guided by the celestial navigation of Lieutenant Commander Elmer F. Stone and others. After repairs, it continued to Ponta Delgada, then to Lisbon, Portugal, on 27 May, and finally completed its journey at Plymouth, England, on 31 May 1919, greeted by large crowds and officials.

Later service and preservation

Following its historic flight, NC-4 was flown back to the United States aboard the USS *Aroostook*. It undertook a victory tour, including a notable presentation in Washington, D.C., where its crew was honored by President Woodrow Wilson. The aircraft was briefly used for further testing and training before being retired from active service. In 1920, it was dismantled and placed in storage. Recognizing its immense historical significance, the Smithsonian Institution requested its preservation. NC-4 was restored and put on public display, initially at the Smithsonian's Arts and Industries Building. Later, it was transferred to the United States Navy for exhibition at the Naval Air Station Patuxent River. Today, the meticulously restored NC-4 is a centerpiece exhibit at the National Naval Aviation Museum in Pensacola, Florida, displayed alongside other legendary aircraft like the NC-1's sister ships.

Legacy and honors

The flight of NC-4 was a monumental achievement that captured the world's imagination and paved the way for future milestones like the non-stop crossing by Alcock and Brown in their Vickers Vimy just weeks later, and ultimately Charles Lindbergh's solo flight in the Spirit of St. Louis. The crew, led by Albert Cushing Read, received the Navy Cross and were celebrated with a ticker-tape parade on Broadway. The aircraft itself was awarded the inaugural Mackay Trophy for the most meritorious flight of the year. Commemorations include a United States postage stamp issued in 1969 for the 50th anniversary, and a monument at Plymouth, England. The flight proved the feasibility of transoceanic air travel, directly influencing the development of commercial aviation and global air routes, and cemented the role of the United States Navy in pioneering long-distance flight.
