I was walking home in South London and I saw a object move up and accelerate immediately. About 30 seconds later men in black turned up and asked me if I was feeling ok etc. Yeah, I was kinda aggressive towards them cos what Id just saw was crazy but they were ok. This sounds nuts but it actually happened, all of it

South London, UK, 13 June 26, around 7pm. Flying very quickly across the sky in a straight line. Could only grab one photo in time. Anyone knows what this is?
