Close examination of a navigational of the area reveal ed that the radar r ay does come close to several :;:-~ints on the terrain, but the Moving-Target-Indicator operates to remove non~oving objects and should have had no difficulty in discerning the ~:~ing object. If it remained at an altitude of 8000 feet, the ob~erver ild have s een it 'rise' above the hills to the south, near Lake Almanor. L~e hills there have an altitude of 6000-7000 feet. On a straight northerly c:Jrse, the object would have been visible under ideal conditions until i : passed ~over the hills just south of Klamath Falls. The southern range o~ hills is about 30 from the observer, the northern range about 50 ID4 f~J= t hel observer to the north, and also about 20-30 ~n~ from the h Falls airport, the largest one within several hundred miles. -: ~ 5ct \.JaS wit!::::.!': o!:e hundred miles of this a irport at the time the C::":s:-::- tiif,-f. lcs;. c::mtact with it, and heading directly for the airport. Tb~= :?.~t a l one rules out the possibilit y of a truck being the object sighted, a~= :los9 scrutiny of the map reveals no roads on which a truck might have visible to the radar beam at the necessary itt altitude. I leave open the ~ questlon as to whether the radar will pick up a speed of 20 mph. A talk with a friend who bas had piloting exp erie nce revealed that it i s e:rt-irely possible for an airplRile to be flying aL that altitude, at that i~ that vJea ther, headigg for the Klamath Falls airport. He suggested -:h e landing ligr.ts on some f, military craft are comparativ0ly large, a.:::.: could a ppear much larger due to diffraction as it passed through the snmt .
