MR. SPROULL: What was the approximate size of the object?

MR. GLOVER: The size, as near as I could judge, would be a weather balloon at 2,000 feet. I am POSITIVE it was not a weather balloon.

MR. SPROULL: What would you approximate as the speed?

MR. GLOVER: That I wouldn't know except that it travelled about 25 or 30 degrees at approximately forty-five minutes to an hour.

MR. SPROULL: In what direction did it move?

MR. GLOVER: Overhead directly into the sun.

MR. SPROULL: Did you think it might be a reflection from anything?

MR. CLOVER: I thought it might be a reflection from the sunlight at first but then I couldn't account for the blue tinge.

MR. SPROULL: Did it glint or sparkle?

MR. GLOVER: No, it didn't sparkle at all. The light from the object was constant with a constant intensity but changed as the sun set lower until it turned toward an orange color. As the sun was setting, it became yellow and after the sun completely dropped, it became orange color. I was just observing this particular change of coloring, when it disappeared completely.

MR. SPROULL: What was the manner of disappearance?

MR. GLOVER: It disappeared like the turning off of a light. I was looking directly at it, when it seemed to disappear as an incandescent light when one turns off the switch. There was no expansion and no change in dimension whatsoever. That is the last I saw of the object.

MR. SPROULL: Any tactics employed during flight of object?

MR. GLOVER: No change in altitude or direction.

MR. SPROULL: Was there any sound to this object?

MR. GLOVER: There was no sound whatsoever.

MR. SPROULL: Was there an exhaust trail?

MR. GLOVER: No exhaust trail at all.

MR. SPROULL: Did you notice the object as carrying any lights?

MR. GLOVER: There were no distinguishing characteristics at all except for the bluish light.

MR. SPROULL: Did this occur to you to be something resembling a flying saucer? MR. GLOVER: When I first viewed the object, the flying saucers immediately
