I was stationed at RAF Cosford, nr Wolverhampton, UK during the Spring of 1979 and worked in the hangars mentioned in the video. I came across the video via a link from a search about Dennis Wheatley, he used to belong to a Society called The Ghost Club which is still in existence and has researched ghost sightings on some other RAF stations such as RAF Montrose. The ghost at Montrose is that of a WW1 pilot who died while stunt flying, to this day, staff at the Officers mess will not stay overnight.
You may think this is all bunkum, that is your opinion and I will never deny or decry what you think. My opinion in there is a lot we do not understand and the faster technology progresses, the more space it leaves behind as belief gives way to hi-tech.
My story "The lost Years" http://alsdomain.weebly.com/4/post/2013/01/the-lost-years.html#.UcdCJzvVAW4 is based on fact. The story may be fiction but the background is documented fact.
