You nut... ..no just joking,you`ll find alot of pilots agree and disagree..and many wont say,fact is nobody knows for certain..most sightings can be expained,and most think balloons / weather /gases /test aircraft etc..but theres many that they dont come across..that arnt obvious explanations of ufo`s,..i myself have work for bufora (british UFO research association) for many years,and some off the work ive had to do to find an explanation is beyond reason..yet..you do the work,the interviews,the study,the samples,the scientific bits and and it turns out that it wasnt a ufo but some very obscure reasoning...then you have a percentage that you just cannot find reason,pilots are very unsure what to do..if they come forward they get alot of problems thrown at them,and a small few have been known to loose there flight status..yet most pilots are the best source,they have no reason to lie,they know what they see and what traffic is in the area and the capabilities of aircraft..unfortunatly we can belive in god,religion,ethics if any of war..we can stand by and watch countries starve or be wiped out,mankind can do alot...but belive other life out there...is one thing most wont accept...until a little green..(ok grey) man turns up on earth,with a shiny spaceship and secrets of the universe...and then we`ll probably just shoot him anyway.
and if there hostile...dont worry..we got EF2000 TYPHOON on our side.
