Black Triangle over Wadworth UK 1994/95

This was quite a while back in about 1994/5, i was out with some friends at night in my cousins car (a crappy little metro) when we stopped of at Thrybergh cemetery to smoke a cigarette.  We were on our way to Doncaster to drop one of our friends off and it was about 10pm. Looking up at the night sky i was pointing out constellations when accross the sky came a shooting star, however this shooting star stopped dead on the horizon.  We all thought this was strange that something traveling at that speed could stop dead as it did.  My friend from Doncaster was training to be a civil engineer at the time (since passed) and concluded that maybe this was a star that we didnt notice before!!!  I reported what i had observed to RAF Finingley, needless to say they did not take me seriously and cut my information short.
We arrived at Doncaster and dropped of my friend and decided to take a different route back to Rotherham Via Wadworth, Tickhill, Maltby (the A60) mainly because it was getting late and my cousin could put his foot down.
While traveling towards Wadworth Hill where it goes over the A1(m) we began to notice something to the left hovering over a field.  As we got closer we noticed it was Triangular in shape, Black (but it was night) with lights in each corner and more lights in the centre.  I cant really remember what colour the lights were but i do remember winding down the window to listen for engine noise.  I wanted to stop but my cousin did not. Arriving into Tickhil i managed to get my cousin to stop the car so that i could use the phone box.  I rang RAF Finningley again expecting the same reception, however this time they asked me questions which seemed to be set. I.E. where in the sky, location etc.
After getting home i left the subject on the back burner.  A while later, possibly days or weeks i recieved a letter in a brown envelope.  With marking On Her Majesties Service.  I opened it and read a type set letter stating that what i had seen was one of many things: flock of geese, car lights, plane.......
This was all around the same time that the Belgium air force were chasing Black Triangles off their air space and others were seen over Yorkshire.
