UK signting - A pitch black object against the background grey of the sky, followed by a triangle of lightsAt around 11pm my parents were sitting outside relaxing after work. I went outside to join them and my Dad told me he had just seen a strange object pass accross the sky. I asked him about it and he said he was looking up and saw an object that was pitch black about the size of an adult thumb at arms length move across the sky very fast and blocking out the background grey and all stars as it went. It moved without a sound. I didn't see anything but then about 5 minutes later at high altitude a triangle of red lights moved across slownly and silently. It had one flashing light and not the usual red/white combination and obvious plane shape you see every day. I'm not sure if this second object was a military plane or something connected to the first sighting but it was weird. Back to the first sighting - my dad described it as "In star trek speak... it was something under a cloaking device - it was a very dark pitch black against the background glow of the sky". I've listed the object as triangle in the report because that is the shape of the other object we saw - my Dad was unable to give me a shape of the first object as it moved quickly.
