Heathrow

Heathrow was a district in west London.

To the north-east of Heathrow was Ealing and roughly to the east was Richmond.

In the 2000s, the London branch of Coldfire Construction, which was secretly operated by the Slitheen, built a technology block in a Heathrow school, using it as a transducer to absorb energy from the Sun and destroy the Earth so they could sell it off. After Sarah Jane Smith foiled the Slitheen at Park Vale Comprehensive School in Ealing, she called UNIT so they would clear up the Coldfire sites across the world. (TV: Revenge of the Slitheen)
