Whirlybirds (1957)

Chuck Martin and Pete "P.T." Moore, are the owners of Whirlybirds, Incorporated, a chopper for hire company based in California. Each week, Chuck and P.T. would find themselves called to help the local authorities in search and rescue, or fly a rich bigwig around. And of course, let's not forget the coolest of helicopters, the Bell 47, tail number N975B.
