Regarding the statistics, we are looking at something pretty self evident. You have regular fliers who are wannabe fighter pilots who enter into the program where they have to receive regular flight training, then military training, then fighter training, and all along the way you have people dropping out. Only the best ever make it. There are a few documentaries out there and I postred a short video clip earlier. If you really want statistics, ask the USAF how many make it compared to how many don't ... ( you don't make the grade by doing worse than the next guy ).
Of course all that being said ... sure pilots can make mistakes. But how do you explain a mistake for the sighting I just posted. This pilot got within 1000 yards, and at one time as close as about 500 yards, in the daytime, and saw it was a flying saucer ... and was on it for about 2 minutes before it just took off ... easily outperforming his jet. Pilots can make make mistakes under ambiguous conditions ( night time, poor visibility, short duration, long range ), But these were unmistakable conditions.
