It was very low. I thought it was a meteor, but far too large. Then thought it might be a plane but there were no flashing lights and it was going too fast and seemed too low for a plane (there is a small airport 3 miles from my house). I thought it might be a plane because I distinctly saw red and blue attached to it. I assumed it was either some bizarre meteor or a crashing plane. Wish I had watched it for longer!
