Hello, sry for the late reply - Ive had to register with this name instead of my old one (purplesofa) as I forgot the password and they couldnt send me a new one.
I was away at University around that time im afraid, but sounds very interesting. I have seen jets fly low through Snowdonia before but just assumed it was training.
I would suggest (although could be expensive) buying a camera with infra-red abilities as they can track heat. Many UFO's have been caught using this technology. I think you may be able to rent from some places.

Im thinking perhaps there is a link with mountains and UFO's. I remember seeing a documentary on the BBC about a place in America, might be Washington state, where people have filmed UFO's going into mountains. The fact you see shooting stars going up could suggest a link with the ground and UFO's.
Keep in touch with any news
