The image below was filmed on an analog camcorder by: Luc Courchesne http://footage.framepool.com/en/shot/271003791-united-airlines-flight-175-aircraft-hijacking-wtc-1-north-tower-wtc-2-south-tower If you look at this video there is a building to the left of the screen which is very darkly lit. It is dark because the camera is pointed toward the sky which is bright, so the camera has used auto exposure to reduced the brightness of the overall image. ie it has increased the shutter speed. I suspect this video camera was operating at a faster shutter speed than all the other cameras and has caught the projection technology in "mid-project". In other words, during the time she shutter was open, the plane was being "drawn", but there was not enough time for the entire frame to be "drawn" in the short shutter speed, so the last part of the projection, ie the wing has been missed.
