It was intended that Connie N7777G, which had lain unused at Dublin since the Spring of 1974, would be refurbished and flown in the second series of Airline. Unfortunately, a technical assessment of the airframe revealed serious corrosion – due no doubt being left outside in a salty air environment (Dublin Airport is only six miles from the sea) had taken its toll.
That, and other issues, meant the second series never got made.
