Seen at least 3 or 4 crazy fire balls and lots of little ones and meteor showers, but have never heard a noise like this in my life. Was so loud I literally fell on the ground.

About 4 minutes after the flash we heard a extremely loud boom followed by about 2-5 minutes of loud thunder-like rumbling... it sounded like a motor rumbling and it was so loud it shook our entire house.

I just saw a couple extremely bright flashes of green light that lit up the entire sky, and my friend saw the actual fireball go across the whole sky and said it was orange.
