Dear Mr. Cates,
Thank you for posting your request on History Hub!
We suggest that you search the CIA Records Search Tool (CREST) for records related to this topic. You also may wish to review the CIA’s Freedom of Information Act Electronic Reading Room. If you do not find what you are searching for already online, we suggest that you file a FOIA request with the CIA.
Also, the Air America Association may be able to assist you with your research.
We hope this information is helpful. Best of luck with your research!
