I live on the 5th floor of a building, the building i live across from a has 5 floors. i looked out my window to see a gigantic dark object with a blue strip of light going horizontally across its side. it went extremely fast over the building and it was very close to the roof. i screamed, “look a ufo!” to my boyfriend but by the time we got up to the window the object had vanished from sight. my boyfriend said he saw a red dot of light at the end of the object but he didn’t see the whole thing because it went so fast.
