.... Yup ... ever since then there seemed to be a lot of Triangle shaped stuff reported. What we saw was definitely a machine with a flat bottom ... We could see the shape against the star field behind it above us ... It was cool ... And as fate would have it ... I had just bought a new Sony Camcorder but decided not to bring it to our giant bonfire we had going ..... Sheesh .... Footage would have been awesome ...
