I was sky watching looking through my cameras viewfinder when i spotted a passenger plane that was flying in a northerly direction. i then spotted a large object that was behind the plane. the object appeared to be round shaped and was following the plane as it flew across the sky matching the plane airspeed. i started taking photographs and watched as the plane and the object flew off in to the distance and out of sight. the object was only visible through the camera viewfinder which was very perplexing. i find it very strange that some of these objects are using stealth technology to blend in to the sky and hide away from prying eyes while other objects are lit up like christmas trees and clearly want to be seen and make there present know. it's very odd. could this be two opposing alien forces, with one try to disclose to the people while the other wants to stay hidden for nefarious purpose. whatever these objects are i know that the government is well aware of their presents in the skies above us. the photograph was taken on the 8th of may 2017 at 11:25 am at newton abbot devon england.
