These photos are from the Pendleton Airport dedication that occurred on June 2, 1934, in Pendleton, Oregon. The event consisted of a day-long parade with representations of historical western United States culture including cowboys and Pony Express riders. The Native Americans present were most likely members of the local Confederate Tribes of the Umatilla Indian Reservation located next to Pendleton.
United Airlines served Pendleton from the 1930s until 1981. The first air mail flight left on June 2, 1934, the same day as the dedication, and the mail was brought to the plane by stagecoach.

Seventy-five 247s were built. Boeing Air Transport flew 60 Model 247s. United Aircraft Corp. flew 10, and the rest went to Deutsche Lufthansa and a private owner in China. The 247s remained in airline service until World War II, when several were converted into C-73 transports and trainers. Some were still flying in the late 1960s.
