Black Triangle Sighting in Northampton, on July 20th 2015 – was driving home and saw this massive triangular silver shaped object in the sky

Was driving home and saw above in front of me for approx 2 seconds a massive object shaped like a plane but more sculptured like the shape of a pigeon gliding. It was massive approx 4 times the size of a normal plane there was no noise and the clouds were low I was stunned and shocked by the size and beauty of this object It then just disapeared into the cloud, there were no markings at all and the colour was an aluminium silver. The time was approx 3.50pm and a member of my staff was with me we could not believe it. I am a great believer in ufos and I can now at last say I believe I have seen one
