It's just a guy who lives at Hart Village on the outskirts of Hartlepool, England. He apparently has loads of recordings of lights acting in a similar way. He goes down the beach or up on the quarry hill and watches out over the town and sees them regular. I take it with a pinch of salt but a couple of lads who wouldn't take the piss went up to his one night and saw the recordings, then they went up to the quarry and saw the lights in the sky and were convinced.
Who knows. I haven't seen any lights and i'm usually up late, and up early.
