"'H' PO& GBNmW. CABIIl.& lD to the incident invol'ring observation ot an Uld.dentifiecl objedt b7 pilot of raoc aircraft on 'Z1 and 28 April 1950 1n the area or K1MW& Air Baee, Japan, we are oonrl.noect that the pilot 1n ch C&ee actuau7 eaw what wae de80ribe4. Ae to what the object actuall7 wae, we feel that it wae not an aircraft or aerod1namic device ot &n7 eort, but wae a visual effect produced b7 ebock waves from o+..her FSOC aircraft in the area at the time each observation was made. In this connection we oll attention to the tact that events took place at 18 000 tt and could have been caused by light retraction in ftl71n8 densities ot air caused by shock , .... vee, such as the Bohl1eren ettecte which can be photographed, or b7 ice c17stals tollitd ae a result or shock waves disturbing super-cooled water Yapor 1n the atmosphere, or a combination ot both these posl'li.bilities. It llbould be noted that the object is described ae having '!no looking like muslin, and having no well defined reflecting aurtac .. , all ot which suggest a not a eolld thing but a "condition" existed in a given volume ot space. It polaroid material s in the path or observation it coulc' have contributed to app-.rancee ot tol'll and color. Thie caee in eoae reepecte it s1m1lar to the excitement caueed b7 "cxploeione" onr Da7ton not eo long ago. The aerocynar.J.ste decided that the "e:xplosione" resulted from shock waves set up by a jA aircraft. All this seems to prove that in advancing the perfOI'Dncee ot aircraft and weapons and in the operational ue of our new weapone, there will continue to be new sights and .,,_,. t.ha t were not aeeociated w1 th the old YNQ ASSIFJ&.l lNG.
