working in Stockwell, London monday 13 March, it was a nice sunny day, about 2 pm sitting outside having my lunch, looking north and watching the planes in the sky, i saw a cylinder coming from the east and going west, but it was not the normal cylinder type that i have seen, this was narrow at the front and at the rear it was wider, with what looked like two compartments, the cylinder was pure white, and did not have wings, I could clearly see the wings on the other planes, but not on this object, it moved smoothly and quietly across the sky, and for a very short time, it emitted a single vapor trail, and then went out of sight

What do you think of this UFO sighting? Could this craft be a misidentified plane or blimp? Or perhaps a top-secret military craft... or even something alien? Share your opinion in the comments below or on social media.
