Mr. Liebeler. Until the time you were discharged?

Mr. Delgado. That's right.

Mr. Liebeler. Did you have access to classified information of any sort in the course of your work at Santa Ana?

Mr. Delgado. Yes; we all had access to information, classified information. I believe it was classified secret. We all had secret clearances. There was some information there as to different codes and challenges that we had to give to aircraft and challenges and so on.

Mr. Liebeler. In other words, if I can understand correctly the nature of your work, you actually worked in a control room?

Mr. Delgado. Yes.

Mr. Liebeler. Observing radar screens?

Mr. Delgado. That's right.

Mr. Liebeler. And when the radar screen would pick up an aircraft, you would then challenge that aircraft?

Mr. Delgado. Right.
