I bought a compilation DVD of six Look at Life aviation films from Video 125 (who also have train films) :
City of the Air, The Spirit of Brooklands, Air Hostess, Controlled Landing, Flying to Work and the Big Take Off.
There is some fantastic period footage of planes, cars, trucks and buildings, including the stylish BEA 1 1/2 Decker coaches, and the high-windscreen AEC tankers.
Most highly recommended for all who remember air travel in the 50s and 60s or who just want to have a look.
