"DC3s / C47s had extended range.
Comment Details Being a qualified pilot with a DC3 rating I have flown many converted C47s. Normally a C47 would have a range of 1,600 miles. Yet they were capable of flying up to 3,800 miles. You can read more about that on page 221 of "The DC-3, 50 years of legendary flight" by Peter M Bowers. In addition, it was very common in the Pacific theatre to fit C47s with internal tanks to extend range. I recall some maratime rated C47s and RD4s were capable of flying 14 hour patrols. Apart from anything. It's only common sense. How do you think the C47s got to Hawaii in the first place? They flew them out, just like they flew out the B17s. "
Maybe in future, DC 3 aircraft coming from stateside should arrive at Pearl?
Here are some going by baby flattop from Pearl to Saipan:(Googled)
