Mountain Time, that he was travelling Eaat t Boise, Idaho, by auto, when the objects were observed to his left, approximately 9t30 o'clock; that the objects were within his sight about five minuteiJ that five or the objects were in "V" formation, flying in a Southwesterly direction, approximately eig~t to twelve or fifteen miles trom his point of ob- servation. He described the objects as being about the size of a B-29 aircraft, silver on top and dull on bottom, end having the shape or a halt-circle with a point in the trent, which was middle of the aro. Persons living in the vioin- it.y or the location from erved the flying ob eta were interviewed but none had ever seen any unidenti flying objeoto. Pilot In- structor ~nd Trainer, Bradley Field, Boise, Idaho, stated that on 24 Apr 49, at about 0900 hours, he was on a flight to Mountain Home, Idaho, in an L-13-B with two passengers and that they observed flying objects about 1,000 teet above his altitude, flying in the same direction aa he but at a raster rate of apeod. He described these objects as being oval shape with a small point in the forward seotion.
