meteor or UFO?

i didn't see it, but apparently there were streaking lights in the sky last night. it was seen here in and north to maryland. the weather service, the Navy, Air Force and NASA all say they have no idea what it was. one person said she "saw something that looked like a comet moving low toward the ground; it was blue in front followed by orange and appeared to be the shape and size of a refrigerator. 'It was just so low. It was like where a bird should be,” she said. “It was definitely heading downward.'"

there was also a loud boom that caused some houses to shake. a sonic boom?

here, one tv station lists emails they received about the mystery light in the sky.
