UFO SEEN OVER NEW DELHI (INDIA)I and my three friends were sleeping on our house's roof. Suddenly one of my friend got up after hearing a sound and started screaming, we also got up and saw that 2 cylinders were flying slowly over our heads emitting green light.First we thaught that it was a helicopter but then we realized that its some cylinder space craft.We watched them for about 3 minutes and then they disappeared.
