SJURCE'S DESCRIPTimJ OF st~HTIMG: SOtECE stated that on 6 ~...ay 1956 at aP- pr~ximately 2205 CST while cheekL~ the sky for weather conditions he noted a bright object in the 'liestern sky below the clouds. 30tB.CE's attention :~s attracted to the object because of its exceptional brightness. SOURCE stated he viewed the object ~or approxi.l'Jtately 50 mL"lutes using 6XJO power binoculars. 30tJ3CE reported the object was sharply outlined. shaped like :,owl, and ri.'1tmed with liehts. Lighus appeared to be individual but were tJ'J nUI:lerous to e .:nmt. (Incl it, Sketch of object) . For the first 30 min- utes or the si~htL~ object appeared to hover in a small portion o~ sky and a. p-pe'l:r:ed to move in a somewba t erra tie manner sir:lil.ar to an aircra..ft in r~ush air. .~t~r a~t JO minutes object appeared to be m in a ~ester~ direction ~nd slowly passed out of sight over t h e ~estern horizon. SOC?.C~ L"'1dicated he sa:-r a few stars but no moonlight was a;>parent. Object appeared bri~hter than the ba.ckgr-,und of the sky and was comparable to the bri5htness of an automobile headli~ht a city block away. Object did not break into parts, ~ive off smoke or change shape. Haw-ever, it did change rightness fror.1 time -to time a.rxi seemed to pulsate or throb. SOU?.C stated he noted an aircraft above and in front of the object in a northwesterly direction fr~ poL'"lt of observation. SOURCE couJ.d not identify or describa the type of aircraft other than that it was not a jet. Object: did not :=nove in front of anything a.t any ti.1'7le during the sighting. 30t;-:tC2 said he t hought the object was solid. There was no audible sound during the sighting. 30URCE indicated he saw only one object and estimated t hat the real size of t he _object at ~b lo~est dimension was approximately 100 feet. SOURC3 -:.;as certain object ap~red to be the size of a nickel held at arms length ~hen viewed thr~u;h binoe,,Jars. S~pP.CE said that if the object were to be eon- ~. strueted of known materials it would probably be of a silvery metallic sub- stance shaped l.tke a bowl. SOGP.CE: reported that he lJas looking northwest !~hen he first saw the object ar.d also ..ras looking northwest ".wh en t h e object disappeared.
