In 1979 researcher Timothy Good interviewed Lucy McGinnis, here’ s what she said some 27 years later:

“Here came this great big ship that looked like a dirigible, she confirmed. And George said, quick, get me up there.I want to go and set up the telescope. So I drove him and Al Bailey up to where he said we should go. I kept looking out of the car and that ship turned and just followed us. And he said, here stop! So I stopped, and he got out, and that dirigible stopped - quite a ways away.
I couldn’t very well judge how far away it was. And he set up the telescope. And after he got everything set up, he said, Now you go back.”

“My attention was attracted by a flash in the sky and almost instantly a beautiful small craft appeared to be drifting through a saddle between two of the mountain peaks and settling silently into one of the coves about half a mile from me. It did not lower itself entirely below the crest, while the upper, or dome section, remained above the crest and in full sight of the rest of my party who were back there watching.
Yet it was in such a position that I could see the entire ship”

Timothy Good asked Lucy how much she was able to see of the face-to-face contact itself; “You couldn’t see very much detail that far away, she explained, they were far away enough to look like fenceposts. But they stood talking to each other, and we saw them turn and go back to the ship. Now I didn’t see (Orthon) get into the ship.And when it left, it was just like a bubble or kind of like bright light that lifted up. Then George went out on the highway and he
motioned for us to come out. He told us that he got too close and his arm had caught in the radiation from the craft. And he suffered from that quite for a while….
You could see where the two of them had walked on the ground. There’s no question about that at all.”
