Nothing has changed one bit about chopper 4 filming an object that was neither a plane or helicopter. https://www.youtube.com/watch?v=GNLVxWUbPDU Minute 2:12, a small object enters the frame from the upper right corner -- Rapid Direct Decent, No Banked Turn This clip of raw, uncut footage was obtained through the Freedom of Information Act by the National Institute of Standards and Technology. The running time is 3:15. At minute 2:12, a small object enters the frame from the upper right corner. It moves in a straight line, swiftly moving from a higher altitude to a lower altitude, coming from a southwesterly direction (around Elizabeth, NJ). The object makes no "banked turn," as famously recorded by so many other cameras - nor has it any visible wings, for that matter. Then, it plows straight into the south side of the South Tower, with explosions emanating from the north side, in the vicinity of the 60th floors.
