Mr. Delgado.

The beginning of 1958.

Mr. Liebeler.

Did you make the acquaintance of Lee Harvey Oswald at any time prior to the time that you arrived at Santa Aria?

Mr. Delgado.

No.

Mr. Liebeler.

You didn't know Oswald while you were in school at Biloxi or Jacksonville?

Mr. Delgado.

No. He was past that already.

Mr. Liebeler.

Oswald had been to these schools?

Mr. Delgado.

Yes.

Mr. Liebeler.

Did you learn subsequently that Oswald had been in school in Jacksonville and Biloxi?

Mr. Delgado.

All of us in MOS 6741 knew that he had been there.

Mr. Liebeler.

For the benefit of the record, MOS stands for Military Occupation Specialty. Is that right?

Mr. Delgado.

Yes.

Mr. Liebeler.

And the MOS number that you have just referred to was what?

Mr. Delgado.

Airborne electronics operators is about the equivalent, I guess.

Mr. Liebeler.

Airborne electronics operator?

Mr. Delgado.

Yes; our job was the surveillance of aircraft in distress, control of intercepts and approaches, and mostly air surveillance and help of aircraft running into problems.

Mr. Liebeler.

How long were you stationed at Santa Ana?

Mr. Delgado.

From 1958, I would say, until November 2, 1959, when I got discharged.

Mr. Liebeler.

So you were at Santa Ann after you completed your training, throughout your entire Marine Corps career?

Mr. Delgado.

That's right.

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 Aria?

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.

Mr. Liebeler.

And it would have to identify itself?

Mr. Delgado.

That's true.

Mr. Liebeler.

And the code or signals that you sent to the aircraft requesting it to identify itself were classified information?

Mr. Delgado.

That's right, along with the range capabilities of the radar sets and their blindspots and so forth and so on. You know, each site has blind-spots, and we know the degrees where our blindspots are and who covers us and that information. That's considered secret, what outfit covers us and things like that.

Mr. Liebeler.

And what was the latter----

Mr. Delgado.

What outfit covers us, that we can see. And as I say, the capabilities of the radars, as I said before.

Mr. Liebeler.

How far out they can reach?

Mr. Delgado.

Yes.

Mr. Liebeler.

And pick up an aircraft?

Mr. Delgado.

Yes; and how high----

Mr. Liebeler.

And how high----

Mr. Delgado.

And how low we can catch them and where we can't catch them.

Mr. Liebeler.

And I suppose all the men who worked, with the radar sets knew these things?

Mr. Delgado.

They all knew. What do they call it now--authentication charts, which is also a secret.

Mr. Liebeler.

What is the nature of these charts?

Mr. Delgado.

Authorization chart is, if we receive an order over the phone, over the headsets--authentication. Pardon me. That's the word. Let's say this order, we can question it. What it actually amounts to, he has to authenticate it for us. Now, he should have the same table or code in front of him that I have. He gives me a code. I would look it up in my authentication chart, decipher it, and I could tell whether or not this man has the same thing I am using. And this changes from hour to hour, see. There's no chance of it--and day to day, also.

Mr. Liebeler.

So that the information, the code itself would not be of any particular value to the enemy, since it is changed?

Mr. Delgado.

It's changed from day to day; no.

Mr. Liebeler.

Did there come a time when you were stationed at Santa Ana that you met Lee Harvey Oswald?

Mr. Delgado.

Yes; in the beginning of 1959. He arrived at our outfit. I didn't take no particular notice of him at the time, but later on we had--we started talking, and we got to know each other quite well. This is all before Christmas, before I took my leave.
