I saw things, and heard statements from Astronauts that I didn't discuss, even with my wife or family. It was like a gigantic trust handed us and we honored it. To this day, I don't talk about everything I heard when I was around the Astronauts, at least not in detail.

There were several incidents that occurred during my tenure as an employee and to several of the Fire Fighters that got all of us thinking about how our government wasn't telling all they knew. For instance, in Building #1 on Johnson Space center, which was Building #2 when I first started work there, most of the north center of the second floor was the "crypto" room. We didn't know what went on in the room, but we did know that we weren't allowed in the room under normal circumstances. However, when an alarm came in at the Fire Station, we responded to the floor of the building that showed up on the enunciator panel at the station, One time, around 1964, we responded to Bldg.#2 to find that the alarm originated from the "crypto" room.
