UFO

last night I was at a friends house, it was 12:48am and suddenly there was this super-dee-duper strong beam of light that came through the window, so we immediately got up, and the really strong light was about 75 yards away and it was floating over a house,it also made no noise at all, then in a split second it flew off so fast you couldnt see it..and disappared. We tried debunking it, with different possibilities, heres what we came up with.

Cars head lights- no way jose- we were on the sceond floor AND we didnt see anyone or any car on the street.

Airplane- Commercial airliner lights blink, and the only plane that can hover over a building and fly away would be the harrier jet, and if it was a jet, we would hear something.

Helicopter- Still, heilcopters arent that fast and once again we would have heard it

Person with flashlight- a flashlight just couldnt be as strong as the light that we saw- it literally lit up half of the room. And we didnt see anyone on the street at all.
If you have any other possibilities post them on comments.
