SEPTEMBER UFO OVER CHISWICK 7.50 PM

Around 7.50 on Friday I was standing by the river Thames. here it is possible to watch planes coming into Heathrow - heading West.
My friend alerted me to a bright orange liquid light in the sky to the West. I checked that it might be a reflection of the sun but the sun had already set. The light stayed bright for about 30 seconds before going out completely. We then made out a black triangular shape that turned to the west and seemed to climb until fading from view. The black object HAD NO LIGHTS at all NOTHING flashed suggesting a landing plane.

It was so bright, the object so pronounced that more people - including the towers at Heathrow must have detected it.

Some one directed me to some footage taken in MAY of a similar light over Chiswick, but in this case it didn't fly off as a black triangular shape.
