dull red traingle forming lights seen travelling north to south in liverpooli reside a very short distance from one of liverpool's city parks, princes park. I was out walking the dog and was heading in a clockwise direction around the small man made lake when i noticed three dull redlights in the sky in an unequal triangle formation. there was partial cloud cover and a break in the cloud allowed a fairly clear view of the stars. plieides, taurus, orion on view, although a fine cloud mist still blaked out the background stars. there was a lot of air traffic - four planes moving at normal speed, but a lot of jet noise. at first i assumed the red lights were plane lights but the formation was moving at exactly the same speed and had no additional standard aircraft lights as did the other planes. the lights appeared to be part of one extremely large craft that was moving far faster than the assumed passenger planes(liverpool airport is a short distance away and there is usually high air traffic) the planes, two of which were going in approximately the same direction(south & possibly chasing) were still on view well after the ufo had dissappeared into cloud. this meant that the object was travelling at least two to three times as fast as the planes, although did not 'zip' out of sight. furthermore, as i was almost around the lake two more dull red lights slowly appeared at the front end of the triangle seemingly forming the shape of two unequal triangles tip to tip.it is viable that the lights were from five individual military jets, but they were travelling very quickly and seemed to be lower than the other planes, although i am not certain of this.if the object was one craft, then it was huge. it was above the cloud base, but semed to dissappear into it, as did the planes due to the 'whispy' nature of the cloud it was heading into.n.b. i have also seen a similar thing several years ago whereby when reclining in another park, sefton park, during partial cloud cover two white lights travelling at the same speed flew by at the same speed. this was for about ten seconds.to clarify...the red lights where the same approx perceived size as medium intensity stars.
