A similar rather shocking finding was reported by Haines, at the NASA Ames Research Center in California. He had commercial airline pilots land a 727 in a flight simulator, using a heads-up display of certain instruments on the windscreen. On certain landing approaches, Haines suddenly superimposed a stationary small aircraft right in the middle of the runway. He expected pilots to immediately abort their landing approach. However 2 out of 8 pilots simply blithely landed through the obstructing airplane. When shown a video of what they had done, the pilots were shocked and incredulous and noted that they should perhaps resign from commercial flying.
