Prompted by centenary commemorations for historic milestones of the First World War in recent years, many museums chose to revamp some of their exhibits celebrating the sacrifices involved in that conflict; the National Museum of the United States Air Force (NMUSAF) in Dayton, Ohio, was no exception. In addition to the special WWI-related events and exhibits which the NMUSAF held between 2014 and 2018 (with an emphasis on US Army Air Service contributions over the Western Front and aircrew training in the United States) the museum also chose to refurbish several of its WWI-era aircraft, albeit after the main Great War celebrations had concluded. These aircraft included the NMUSAF's Curtiss JN-4D Jenny, Thomas-Morse S-4 Scout and a reproduction Avro 504K. The museum's restoration workshop has only so much capacity, and could not focus exclusively on these projects, so it is only recently that they have finally finished the bulk of what they set out to do.
