Witness Account

At first was inside my apartment gaming and all while I heard a loud explosion. Then a minute or so goes by and I hear a vehicle probably police car with there blow horn to stop blowing up fireworks and continue saying it for a few minutes then I hear some guys that are out front having a smoke going wow what is that saying like they think a airplane blew up in the sky so I figured why not go out and look and I was never really a big believer till I seen it. It was as long as an apartment building kinda looker like two buildings put together sideways with no lights on and before a picture could be taken it had slowly back in to the sky and vanished.
