Out in the Pacific we were in rolling seas and I was overhauling the headset on a 1970 Super Course. Had everything out and on the bench when for some unknown reason the ship rolled sharply and the balls went to the floor rolling everywhere in the space. Took a long time, but I found all of them except two. A day later my shipmate came to me with the two missing balls asking me what I thought they came from. Miracle on the Pacific.
