this programme was very interesting
here is what the programme is about

Documentary series examining the most astonishing and baffling UFO stories from around the UK. In 1974, locals near the Berwyn mountain range in Wales experienced an earthquake and reported seeing green lights in the sky. In an incident that would become known as the 'Welsh Roswell', some claimed that a UFO crashed into the mountain and that the government tried to cover up the truth.

Was it on the BBC?

The earthquake and weird light is easily explained - coal gas!

i did not watch tonights programme however a know of this case.
several objects and green lights were seen by different people at different locations, all moving in away that was controlled .
as for coal gas, a large egg shaped silver craft does not appear to be coal gas. what appeared to be called a earthquake was a shock wave caused by a object crashing maybe. that was what local people thought anyway.and i dont think that the locals who say there was many men in black around checking the hill sides . would be interested in coal gas.
why have the mod still not released all they have on file in this case?

Anyone know if it was on BBC and repeated on Catch up T.V!

On Channel 5
