Birmingham - United Kingdom - 03-11-14
Shape: Triangle - Duration: 5 seconds -
Two elongated triangle shaped craft; no noise or lights, one behind the other.
I was looking up at the night sky looking at a group of stars called in layman’s terms the Saucepan which is a group of 7 stars.
The sky was clear with various thin, broken clouds when 2 triangular shaped objects appeared. They were traveling in a northerly direction one behind the other.
Speed, height and size were hard to gauge as there was nothing in the sky to compare them to. My best guess as to the speed would be faster than a commercial aircraft at cruising altitude but not as fast as a shooting star.
I live underneath one of the North Atlantic approach routes into London Heathrow. The aircraft that I see overhead are usually at a flight level of around 26000 feet, these craft did not appear to be that high and appeared to slightly higher than the broken cloud base and you could still see them as they passed through the cloud.
If they were flying at around 5000 feet then I would estimate them to be the size of a Boeing 737 and traveling at a speed of around 500 m! ph. There was no sound evident and no vapor type trail. The shape of the craft was that of a slightly elongated triangle, rounded at the 3 points.
Neither of the craft had any lights and the best way that I can describe their color would be a smoky grey/milky color. They both continued in a northbound direction, the rear craft flying at around the distance of 1 crafts length behind and seemingly at the same height and disappeared in to thicker cloud. All of this observation lasted around 4-5 seconds.
I have been an avid aircraft enthusiast/spotter for the last 45years and know what an aircraft looks like in flight whether it is private, commercial or military irrespective of how high they are flying.
Where I live the aircraft on approach to London are at a height of around 26000 feet but can still be heard in the sky quite clearly, as do the other aircraft which pass overhead on their way to Europe at flight levels of around 33000-35000 feet. These 2 craft were not audible at all.
