Full Description & Details

talking to neighbour looked up and to left and saw a stelth aircraft appear out of nowhere it had tail fins at the end of the craft, air intake pods on top of the wings either side of cockpit.

As this craft approached i could see a kind of large semi circle with a serated ege on the trailing edge of the semi circle , this was located at the front of the triangle and there was a further two at the back end of the triangle.As the craft came towards me this is wen i started to see the black triangle appear ,it was enormous and it blocked out the stars as it went.

When the triangle was above me i could see that it was the blackest black i had ever seen , on the underside of the craft there was no markings whatsoever,there were no rivets to be seen it was so smooth and the edges appeared the thickness of a sheet of paper i remember thinking that it looked like a hole into space and time.this craft and triangle was completely silent was flying at about 30 mph . As i was watching the craft going over i could see the craft cockpit which had one single sheet of curved glass and no reinfocing structures along the glass, What i could see some kind of struts above and below the cockpit as if ashield could appear and protect the glass winscreen on the cockpit. I realised i was looking straight into the cockpit but i could not see anyone piloting the craft, I watched this craft for at least another minute and the craft and triangle disapeared like a light bulb going out.

when i first saw the aircraft come into view it was a gunmetal grey colour and looked unstable as if it had just materialised or had come to an abrupt halt very quickly.Also i live on the flight path to heathrow airport and this craft and triangle were flyng at about 100 ft above ground level.

Can sighting be explained as any conventional man-made or natural object?

black triangle is very advanced technology, Craft was stealth type american aircraft
