unfortunately, no. TWA never operated DC-6's. but it was popular among a lot of other airlines. Today, at least one carrier uses them as cargo planes. Everts Air Cargo. you often see them in Fairbanks and Anchorage
Other times, your hard money, turns into, handbags, shoes, lovely stones, scented candles and designer pillows!
Popped into my local Modelzone yesterday, it being a bank holiday in the UK. Came away with an Academy 1/48 P-47D "Gabreski" for £15 and a 1/48 Academy F-86F "The Huff" for £10.
Both good bargins and could've come away with a lot more much to the wife's displeasure
DC-6. Northern Air Cargo anf Everts Air Cargo operates themI believe I saw one at Anchorage. I thought that it was a DC-7 from a distance but of course I probably could not tell the difference standing under it! It was beautiful and I was thrilled like seeing it took me back to another era.
