The Plane Makers

The Plane Makers was a 60's industrial drama with a lot of kitchen sink elements although the focus was on management. It ran for 3 series (58 episodes). Only the very first (of 16) episode from Series 1 survives. These discs contain that and the 28 Series 2 episodes. It's unknown if the 13 Series 3 episodes will find their way into the hands of the public at this time. Episode 22 from Series 2 is missing from the episode guides so I don't know if there was one or not. 
If you go on the "A-z" website you will see that these are not easy to come by and can be had only at a considerable cost. Mancunian Ken made a great effort to make these available. This show was continued as The Power Game which you can look for here in the future. The 96 or 97 47-minute episodes of Plane Makers / Power Game made it one of the longest TV drama productions of the 60's. Although little of this program takes place in a plane, I do enjoy the cavernous mockup they used for those scenes. If only passenger jets did have 10 foot ceilings! Looks like the inside of a C4-Galaxy. That's Wendy Craig serving drinks.
