Though not entirely on topic its quite similar.
Theres a strange factory type building in South London, its on Streatham High Road on the corner of I think Kempshott Road, SW16.
Its got a bunch of surveillance cameras, a small sentry box type thing and a pretty mean looking fence.
Now this factory is maybe the real place where the Q types do their work. Nothing seems to go in or out of the factory, theres no signs or anything else that would signify a real manufacturer or anything. Theres no way to see inside the building, outside theres a couple of big vans that look similar to an outside broadcast van the BBC might use and I think a fuel pump just like a normal petrol station. I have never seen anything moving the hundreds of times I have passed the place.
I seem to remember it being mentioned on a TV show hosted by Philip Schofield, you could call in and they would investigate by asking the public to call in with their views etc..
A good friend of mine worked at a motorcycle shop a couple hundred yards from the factory and every now and then a guy that worked at the factory would come in a buy parts for motorcycles, my friend asked what they did in there but the guy never told him anything at all. I am not sure how my friend knew that the guy came from the factory, I will ask him sometime.
If anyone has any knowledge of this place and what the guys do in there I would be really interested to know.
PS. only twice in my 30+ yrs of living in the streatham area I have seen HUGE MISSILES being transported in the early hours of the morning. Both times it was a single missile/rocket being transported with a police escort. They were driving along Crown Lane towards Streatham Common then down the side of the common. It just occured to me that maybe they were heading for the secret factory. These rockets were HUGE, only missing the top of the lamposts by inches and they were laying horizontally on the flatbed truck, I know they were not say huge boilers or anything as you could see the nozzles for the motors at the back, I would estimate they were at least 70ft long and it was not your average HGV that was hauling them.
I saw one of these on my own and another time was with a friend and he saw it too, so I wasnt hallucinating, we actually ran so we could get a better view. I have always wondered why it would be necessary to move missiles through a very built up area in the middle of a city, as far as I know there are not any launch sites round here.
Again if anyone knows what these were doing please let me know.
