The first Alaskan Aerial Survey Expedition was conducted between June 6 and September 24, 1926.
They used the tender Gannet (AM 41) and the barge YF 88, housing a photo lab and mobile base for the expedition, and three Loening amphibians. There were 12 officers and 100 men. The purpose of the expedition was to survey Southeast Alaska for the Department of the Interior. During the summer over 15,000 square miles were mapped.

1932, July 5 - Mattern and Bennett Griffin flew "The Century of Progress", a Lockheed Vega, powered by a Pratt & Whitney Wasp engine, from Floyd Bennett Field, New York, to Harbor Grace, Newfoundland, and then non-stop to Berlin, Germany, in 18:41 hours. This failed round-the-world flight attempt ended in an emergency crash landing at Borisov, Belarus, USSR, on July 7, 1932. They did, however, set a record for crossing the Atlantic Ocean: 10 hours, 50 minutes.
June 3, 1933: Mattern flew a rebuilt "Century of Progress", largely a different aircraft, and this time solo, from Floyd Bennett Field across the Atlantic. On June 14, 1933, he made a forced landing in Siberia, where the "Century" was abandoned. He was eventually rescued by Eskimos and flown to Nome, Alaska, by Sigizmund Levanevsky.
