EVANS after the brightness of the fireball decreased, I could look
(CONT'D)
back up through the rendezvous window and see what to me was
a bright spot in the middle of the
kind of like a tunnel with
tunnel. Way down the tunnel, way back behind, I could see
the fireball.
CERNAN The only unusual sighting I can recall during landing or
recovery is when the CMP looked out the window and saw the
superstructure of an aircraft carrier and said, "Oh, we've
got a tin can with us."
EVANS Well, it was kind of foggy on the windows.
SCHMITT Transearth we had only a small crescent of an Earth and it was
not feasible to do any extensive weather observations. We
had light flashes just about continuously during the whole
flight when we were dark adapted. I had one which I thought
was a flash on the lunar surface. That one period of time
when we had the blindfolds on for the ALFMED experiment there
were just no visible flashes, although that evening, that
night, before I went to sleep I noticed that I was seeing the
light flashes again. $So, it just seemed to be that one
interval either side of it where the light flash was not
visible to myself or to the other two crewmen.
