I've been watching a lot of Ice Pilots lately so much that I forgot that they are a real airline and I've been wondering about their fleet. From what I gather the DC 4 and the C46 are both used as Cargo Planes but both seem to have a set role. Now I have no idea what these roles are and I'm very curious what the big difference between the two planes are. Plus considering they use the Electras now do they still need the old Warplanes or do their piston engines give them a special trait that justifies their continued service?
