Near sunset, a civilian reported a fairly small UAP object shaped like a "crate" that was observed from the ground, being not too high traveling north, and appeared to have various rainbow colors. At first the UAP object appeared to be reflecting the sunset, but when it changed position, it retained its color. There were no apparent means of propulsion, yet the object did not seem to "drift."
There were no photos taken and no physical evidence.

Weiser, Idaho UAP Sighting
Source: Project Blue Book File - 10073 Record
"On the evening of June 12, 1947 at 6:15 pm, a neighbor and I, returning home from another neighbors, glanced into the sky toward the west, and saw what we thought was smoke from an airplane. She mentioned that she had never seen that before, so we stopped to look and listen, thinking we would see the plane, but there was no sound, so we kept looking until we saw a tiny object from which the vapor emitting.
It was so far away we could not determine the size or even the shape. Its only identity was a glisten in the sun. We watched this for a few seconds, when from the general direction of the sun, another object shot into the sky. It followed the general direction of the first, shooting up and down before settling to a south-easterly course across the sky, where we followed them until they were only a glisten, and the vapor could no longer be seen.
After the objects were gone, we continued to look and to watch the vapor which had been left, which now looked like clouds but kept a shape, and this shape seemed to glide across the sky to the east, where there was a black streak leading to the horizon. The vapor stayed in the sky for over an hour."
Project Blue Book hypothesized that this case may have been a double-fireball meteor event, but that was never proven.

There were no photos taken and no physical evidence.

An experienced civilian pilot, Dick Rankin first sighted 10 UFO objects flying in a V formation to the east while at home, with one of the objects straggling behind. Later on, 7 more UFO objects were seen flying a V formation come back the opposite direction.
Dick was of the opinion that these objects were probably XF5U-1 "Flying Flapjack" United States military planes. This was the same conclusion from Project Blue Book.

Mount Rainer, Washington UAP Sighting
Source: Project Blue Book File
On June 24, 1947, private pilot Kenneth Arnold claimed that he saw a string of nine, shiny, large UFO's or UAP, flying west past Mount Rainier at speeds that he estimated to be at least 1,200 miles an hour, or Mach 1.56, but maybe up to 1,700 miles an hour. He clocked the UFO's going 47 miles in 102 seconds.
The UFO objects appeared to dip and twist. Kenneth Arnold witnessed the UFO objects for 2 to 3 minutes, and they were about 25-30 miles from his aircraft. Kenneth Arnold estimated the UFO objects to be 45-50 feet long.
J. Allen Hyneck notes in this file that, "In all probability, therefore, objects were much closer than thought, and moving at definitely sub-sonic speeds."
Project Blue book concluded that, "the objects in this sighting was a mirage. Kenneth Arnold's statement concerning how smooth and crystal clear the air was, is an indication of very stable conditions which are associated with inversions, and increase the refraction index of the atmosphere."
This was the first UAP sighting in the United States, that received nationwide attention after the end of World War II. Kenneth Arnold's description of the UAP objects also led to the media creating the term "flying saucer" as a popular description for UAP in the future.

Military observers from Maxfield, Alabama, sighted a star-like UFO object on a clear moon-lit night, moving east and then south at a great height, for about 5 to 6 minutes from the ground. The object was a little more brilliant than a star and had frequent bursts of speed, it was zig-zagging, and made no sound.
Project Blue Book concludes that this sighting could have been a synoptic weather balloon.

Lake Meade, Nevada UAP Sighting
Source: Project Blue Book File - 10073 Record
1st Lt. [name redacted in black] departed William Field, Arizona at 1400 Central Standard Time, in a P-51 bound for Portland, Oregon by the way of Medford, Oregon. At approximately 1515 CST, at an altitude of 10,000 feet and a speed of 285 miles per hour, and about 30 miles northwest of Lake Meade, Nevada, the Lt. observed 5 or 6 white, circular UFO objects at Four O' Clock, at an altitude of 6,000 feet.
​
The Lt. said that the UFO objects were flying very smoothly and in a close formation. The estimated size of the objects was 3 feet in diameter. The Lt. stated that he is not sure that the white objects were not birds, since the rate of closure was very fast. However, the Lt. states that he was certain the white objects were not jets or any conventional type aircraft, since he has flown both types.
​
The Lt. was very sincere in the explanation and was not the exaggerating type. He merely stated what he saw and has drawn no conclusions about what the white objects were. Project Blue Book concludes that the UFO objects were a balloon cluster.
​
There were no photos taken and no physical evidence.
