UFO Sighting in Boxgrove, England on 2017-11-12 18:45:00 – I was looking out window to what i thought was a low plane but it suddenly shot off with a huge beam of light so fast and disappeared

I was looking out my window as i usually do on a afternoon before locking the house up. i noticed low flashing green and red lights just above the houses in my street. i thought "wow that planes so low" considering i live 3 hours from any airport. then within the time i called my partner it shot away with a huge beam of light in a south westerly direction, i ran outside to see if i could still see it but it was gone. it lasted about 30 seconds. i was in shock and awe of what i saw i was reduced to tears and shaking. the object was big and teardrop shaped. the air was crisp and cold and so silent outside. i felt like i had interrupted it and thats why it flew off so quickly.
