N number 30000 has been worn by five different DC-3s. NC30000 was issued regularly in 1941 to a DC-3A (c/n 4809) which the Douglas company decided to keep as a demonstrator and executive transport. Douglas kept the mark and used it for the first remanufactured DC-3C (old c/n 13825, new c/n 43073) and then for the first Super DC-3 (c/n 6017/43158). When that one was sold, the reg of the plane in the photo, the second Super DC-3 (c/n 4122/ 43159) was changed from N15579 to N30000. Another Super DC-3, VC-117D BuNo 17175 (c/n 12779/43301) also wore N30000 in the 1990s. Photo from: San Diego Air & Space Museum
