There's nothing to do with aviation in this film of egg gathering on Bempton Clifs in Yorkshire's East Riding, but it's intrepid all the same. It follows a group of 'climmers' - four men and one woman - who take turns to scale the sheer chalk cliffs, suspended from ropes and basic harnesses, with the North Sea lapping hungrily some 400ft below. Dizzying viewpoints and some colourfully-worded intertitles heighten the inherent drama - not for the faint-hearted!
Farmers whose land adjoined the cliffs had the right to harvest eggs, which was lucrative (if absurdly dangerous) in the 1920s, with the eggs doing a roaring trade among professional collectors, or sold for food - London hotels were apparently particularly keen. During WWII, the egg collectors' efforts were applauded due to the short supply of hens' eggs. But by the mid-50s the practice had been banned, and today Bempton Cliffs are a Royal Society for the Protection of Birds nature reserve.
