A child of the Second World War who has lived in West Drayton all his life has been recalling his experiences working in a top-secret building.
Ron Parker, 70, who lives in Whitethorn Avenue, West Drayton, worked in the Shock and Vibration Department at the Admiralty Research Laboratory.
The building was eventually knocked down to make way for flats which still stand at Admiralty Close, West Drayton.
Mr Parker said: "Anything that was built for a boat had to come to the ministry to be tested.
"It was a massive factory, full of machinery for the Royal Navy.
"Most of the people who worked there were highly skilled people; anything the Ministry of Defence wanted could be made by the people in there.
"It was full of very intelligent people with highly confidential jobs.
"The railway used to take goods directly into the building and I remember there was a powerplant opposite."
Mr Parker was born in a house in Kings Road, West Drayton, where he grew up before moving to his current address 27 years ago.
He had seven siblings and his family were among the first to move into the Kings Road houses before the war.
"During the war everyone thought Hitler was trying to bomb Heathrow, but he was actually aiming for the Admiralty - that's where our defence systems were.
"So they had soldiers on guard all night long, but even up until when it closed, the security was very high there.
"The Americans were based at Porters Way in the war which is also flats now.
"I remember the street party which marked the end of the war very well, even though I was only five at the time.
"Everybody who lived in Kings Road, Queens Road, and Porters Way got an invitation and it took place at the junction of Kings Road, and Queens Road.
"The women got everything ready and put it all up.
"It was a great atmosphere, and full of big families as it was in those days, and everybody knew each other."
