Large fire close to Heathrow Airport is disrupting the air traffic as the visibility is obstructed due to the smoke that blows across the runway.
Around 100 firefighters were battling a huge grass fire near Heathrow Airport.
A London Fire Brigade spokeswoman said that the long stretch of dry weather was probably the cause of the blaze.
Due to large fire to SE of the airfield & in order to preserve flight safety we will be changing runways from 1800Hrs, arriving Rwy 27R & departing Rwy 27L. Please accept our apologies for any inconvenience caused. We will resume the normal alternation pattern as soon as possible
