When i was a kid my sister claimed she saw a triangular shaped ufo, this was also seen by many from our village including a policeman who then went onto become a big ufo researcher and write a book.
The strangest thing i have seen one summers day (not a cloud in the sky), was a black cigar shaped thing zoom through the sky, i remember questioning myself and settled on the theory that it must have been a plane but the sun was reflecting on the wings causing them to blend in lol (sounds daft now i wrote it down).
And lastly my brother who is a complete sceptic on all things paranormal saw a triangular craft a couple of months ago, he was taking his son to football when he spotted it from far off, he noticed it looked different and pointed it out to his son. It flew towards him and straight overhead and was quiet low, i think he said it was white or pale silver with lights on (during day). This ufo sighting also made the news after been spotted by lots of people.
Once when I was riding home in the car with my Mom, I saw this triangle shaped thing, it was glowing and hovering. My Mom asked me if I saw it, I said yes. We both got out of the car and it was still there, it was too low to be just a plane or something. We were 99.9% sure it was a UFO, but no one really believed us because it was too dark outside to get photos. =(
