One blue-green object was observed by four witnesses two of them independent for ten minutes.

Hynek quotes the witnesses:

. . . my friend, who was driving the vehicle, said, "Do you see what I see?" . . . This odd-looking object looked like a stunted dill pickle. We agreed we didn't know what it was.

While we stopped there, a half ton truck came along with two men in it -- they were taking a load of hogs into Calgary. The one man asked us if we were having trouble. We said no but showed them the object and asked what they thought of it. One of the men said, "Oh that must be one of those flying saucer things . . ." However, I sat around and thought about it all day, and that afternoon I decided to phone the control tower at Calgary Airport to see if they knew anything about it. They said they didn't.

The color was greenish blue. It seemed to have a sort of fluorescent glow to it, but it wasn't really a fluorescent color as we would know it. I would say it was more like the writing on these signs along the highway that say, "Calgary (so many) miles," something like a scotch light with a green background. Actually no lights on it whatever….There was not a bit of sound, but we could hear the sound of the airplane taking off from the airport at Calgary.
