Getting some TLC in the TransNorthern hangar.

One of two C-117D/R4D-8 Super DC-3s operated by TransNorthern. This aircraft is a freighter while the other is set up to carry passengers.

N30TN the sole surviving civilian Super DC-3, with all others being former US Navy C-117D/R4D-8's. Wearing Douglas company colors, her wings had been removed for a mandatory inspection before the start of another season carrying passengers to the Alaskan outback.

Still wearing the colors of former owner Lee County Mosquito Control District, this aircraft was reportedly sold to a museum that planned on flying it to the June 2019 Daks Over Normandy event in Europe. From this photo, it obviously never made the trip.
