#VEDay75: Fog of war: how gas helped bring 10,000 airmen and 2,500 aircraft home safely 


Allied aircraft faced many hazards during the Second World War – and secret research pioneered by the gas industry helped to win the battle against one big danger presented by Mother Nature.

The Gas Light and Coke Company was the first to demonstrate, on a large scale, that fog could be cleared by the application of heat. Its research department and laboratories at Fulham undertook secret research for the Government, including assisting the Petroleum Warfare Department in building the final (petrol-fuelled) system, installed at airfields at home and on the Continent.

What came to be known as Fog Investigation Dispersal Operations – or FIDO to use its commonly used acronym – is said to have saved 10,000 airmen and 2,500 bombers.

We’ve worked with Professor Russell Thomas, chairman of the history panel of the Institution of Gas Engineers and Managers, to produce this special series of stories for #VEDay75.

Cadent is the UK’s largest gas distribution network with a 200-year legacy.  We are in a unique position to build on strong foundations whilst encouraging the curiosity to think differently and the courage to embrace change.  Day to day we continue to operate, maintain and innovate the UK’s largest gas network, transporting gas safely and protecting people in an emergency.   Our skilled engineers and specialists remain committed to the communities we serve, working day and night to ensure gas reaches 11 million homes from Cumbria to North London and the Welsh Borders to East Anglia, to keep your energy flowing. 

Future of Gas: Here at Cadent we support the Government’s plans to reach Net Zero by 2050. That means we’re backing the introduction of hydrogen as a low carbon alternative to natural gas for the future. We know people love the controllability of gas and, with our network already in place, it makes sense to switch to the lower carbon alternative offered by hydrogen, which we believe can keep homes and businesses warm for generations to come.
