EUROFIGHTER Typhoon jets will fly over RAF Northolt this weekend in preparation for when they are based here during the Olympic Games.
A pair of the supersonic fighter planes will conduct two sorties at 1,000ft over Hillingdon between 7 and 10pm on Saturday (21) - but will not land.
Although residents will be unfamiliar with their sound, a spokesman for the RAF base said the jets would be less noisy than their Tornado cousins, which sporadically visit the area already.
"Typhoons are very capable aircraft and will have climbed to a much greater height by the time they fly over the station," the Gazette was told.
"Residents will hear the Typhoons but I don't envisage it will cause too much disturbance."
The planes are able to travel at supersonic speeds without the need for afterburners, making them slightly quieter than comparable aircraft.
During July, August and September this year several Eurofighter Typhoons will be based at RAF Northolt, in case of any terror alert during the London 2012 Olympic Games.
Pilots will need to familiarise themselves with the base and the local landscape before then.
