I went into the back garden to have a smoke at night. i bent over to pick up something up and something caught my eye but as i stood up i heard something instead it was air like as if a large aircraft had just gone over the top of the house. i no i don't have my phone on me to catch the moment and with running into the house i would miss what ever could happen if anything. so i'm stood there listening to this air it's more of a whirl of air and it's getting louder so by this time i'm thinking it a plane in trouble becouse about 3 miles away we have raf weston on the green its a old air field that's being used for army's paras practice night jumping and you can tell if it's a plane becouse of the flashing under carriage lights, our town is used to planes flying about because of u.S air base upper hayford which has closed down, anyway this air noise stops and just above the houses a huge black (blacker then black) rectangle craft flys past me it's a dark night and my eyes had to re-adjust to see the black craft, the ship is the size of a football field high by 3 football fields long that's the only way i can describe the size and the colour it was black really black i've never seen anything as black as that before the only light was the reflection of light coming from the houses and 2 lamp post, it flew past me i saw the back then the wind started again and just flew on end of that but i'm now having trouble believing what i saw its 3 years later on and it's still playing on my mind. i try to work out how it would fly and other questions constantly going over it in my mind also i don't think this is the first time i've seen it i'm sure i've seen it when i was younger i do believe this is the 3rd time. not sure on who to talk to about this. if need be i will do any test.Anything
