Dan-Air 1960's schedules into Teesside
Can anyone tell me exactly when Dan-Air stopped their initial scheduled services into Teesside (begun in 1965)? These ran NCL-MME-LPL-CWL-BRS, with DC3, and later Ambassador as far as LPL. They appear in the summer 1969 timetable, and have vanished by July 1970, after Nord 262 introduced. (Dan-Air resumed Teesside schedules again from 1973).
