Mr. Jenner. That is the clearance about which you speak when you talk about Oswald having lost it?
Mr. Thornley. Oswald, I believe, had a higher clearance. This is also just based upon rumor. I believe he at one time worked in the security files, it is the S & C files, somewhere either at LTA or at El Toro.
Mr. Jenner. Did you ever work in the security files?
Mr. Thornley. No, sir.
Mr. Jenner. And that was a level of clearance——
Mr. Thornley. Probably a secret clearance would be required.
Mr. Jenner. It was at least higher than the clearance about which you first spoke?
Mr. Thornley. Yes, sir.
Mr. Jenner. The clearance that you had in mind of which you first spoke was the clearance to operate radar detection devices?
Mr. Thornley. Right.
