ALBANY -- FOX TV News reported on October 21, 2002, that a spear shaped object was caught on film passing above Albany International Airport during daylight hours as a commercial aircraft landed at the airport. The spear shaped object was moving at high speed and could be mistaken for a missile, but none was known to have crashed. The FBI is attempting to determine the cause of the video sighting.
