Thought there was some revealing data found here regarding a 'reality check' on just how many people actually report their UFO sightings (I know I didn't) and when it comes to military/civilian pilots there's always been serious concerns about under reporting bias due to fear of ridicule, perceived competence, job security etc. After the Robertson panel led to the implementation of the JANAP 146 directive which basically made the reporting of UFOs to the American public an 'act of espionage' then suppose fines of up to ten thousand dollars (and/or one to ten years in prison) also deterred quite a few pilots from discussing their experience. Over the years there's been some truly revealing UFO surveys and polls conducted on professionals in the aviation industry (including this one involving 1000 radar operators) but did think there was a really relevant report below concerning 'under reporting bias' from NARCAP's Ted Roe. Report (PDF File): • Sticking with NARCAP also thought this was a pretty awesome interview with Dr. Richard F. Haines. The Pentagon's Al Chop also pops up in the vid below but there's a good section on pilot UFO under-reporting featuring NICAP's Richard Hall and NARCAP's Richard Haines found around 10:30.
