The original caption suggest the Edwards test centre used three R4Ds, one at a time, between 1952 and 1984, and that this was the second one between 1956 and 1979. One of their jobs was to check if lakebeds were dry enough for X-plane emergency landings. Last registration of this airframe, XA-ROM. Photo from: NASA
