Even when the US Air Force learnt that UFOs were, generally speaking, flying vessels which were not from our civilizations, and had a crew aboard, the US Air Force would follow a general pattern-a UFO is sighted on military radar at an Air Force base. A small jet plane is sent to investigate. When the flying object is discovered to be a flying craft; the jet plane pilot is ordered to make the object land, by any means, even by shooting it down with a missle which the jet interceptor plane is carrying in multiples. On the old STAR TREK tv show, there is even an eposide, filmed on Jan. 26, 1967, entitled:"Tomorrow is Yesterday" inwhich the Enterprise is hurdled back through time, to 1969, is picked up as a UFO on a military radar at an Air Force base, a jet interceptor is sent out, sees the starship flying through the sky, reports to base; then the Air Force pilot is radioed with the order to stop the UFO from escaping and to shoot it down if necessary. So, even in 1967, a Hollywood writer was well aware of the US Air Force's Shoot down UFO policy, and wrote it into a STAR TREK story. When UFOs are seen in the sky, they are in danger of being forced to land by US Air Force pilots in jet fighters who will shoot them down and kill aliens on board. Air Force pilots of other countries probably are ordered the same type of UFO policy. Air Force pilots of the world should refuse any orders to shoot down UFOs because any alien life forms on board would be murdered. UFOs can be doing absolutely nothing wrong, simply flying high in the sky observing the earth, even just flying over vacant, desolant land and are in danger of being shot down and the alien crew murdered.
