A radio at the Montrose Air Station Heritage Center in Scotland has been picking up radio broadcasts from the WWII era.
The vintage radio set is kept in a recreation of a 1940s room. Several people have heard Second World War era broadcasts including the big band sound of the Glenn Miller orchestra and speeches by Winston Churchill. The broadcasts come on at random and can last for up to half an hour...
"It plays Glenn Miller, and that's what everyone has heard. It is very faint and you have to put your ear to it, but that's what it's playing.
"It's not just one of us who's heard it - most of us here have. We are talking about highly educated, reliable people.
"My wife Aileen was with me when we heard the Glenn Miller Orchestra last weekend. She's a physicist and not predisposed to believing in things like this but no-one has an explanation.
The fact that the radio is not plugged in will cause some people to be skeptical, and assume that an audio device has been hidden inside the radio case. However...
Technicians who examined it removed the back, but found "nothing but cobwebs and spiders".
