Between 11:00 a.m. & 11:20 a.m., Robert F. Smith, a World War II bomber pilot, saw 6 unidentified flying objects about 10 miles West of Shafer Butte.
Smith at the time was driving from Caldwell to Boise.
5 of the objects were flying in a V formation at an estimated 13,000' altitude.
They were the approximate size of a B-29 aircraft, silver on top and dull on the bottom, and the shape of a half circle with a point in the front.
The objects were in view for approximately 5 minutes.
The 5 objects appeared to be in a descending spiral formation and seemed to be linked together because they remained in almost perfect formation.
They then changed course and took off into the sky at high speed.
No commercial, military or private aircraft were known to be in the vicinity where the objects were observed.
