To Whom It May Concern:

Pursuant to the Freedom of Information Act, I hereby request the following records:

A copy of US Air Force OSI files on Leonard H. Stringfield (Born: 17 Dec. 1920; Deceased: 18 Dec. 1994), a DuBois Chemical executive from Cincinnati, Ohio and director of the group Civilian Research, Interplanetary Flying Objects (CRIFO), as well as the publisher of its monthly newsletter, ORBIT.

Stringfield claimed to have cultivated multiple anonymous government sources for his CRIFO investigations, many USAF personnel, several associated with Wright-Patterson Air Force Base in Greene County, Ohio.

Stringfield is deceased. See "The Cincinnati Enquirer" of 20 Dec. 1994 (link and attachment): https://www.newspapers.com/clip/29648995/the-cincinnati-enquirer/

Stringfield has been deceased for longer than the 25-year period after which Mandatory Declassification Review (MDR) is acceptable under E.O. 13526, Section 3.5(e) (https://www.archives.gov/isoo/training/mdr). Much of the potentially pertinent records on Stringfield's activities however, will stretch back still farther, some 50 years older of more. This is pertinent because, under Executive Order 13526 (https://www.archives.gov/isoo/policy-documents/cnsi-eo.html) signed by President Barack Obama in December 2009, and still in effect, classified documents 50 years or older, must be declassified unless they include the names of confidential intelligence sources or information on weapons of mass destruction technology.

If some records may be released immediately while others require a review, I respectfully request a two-tiered release. I am making this request as a member of the news media, and request classification as such, including a fee waiver. I have previously written for Gizmodo, Slate, The New Republic, the New York Review of Books, Inverse.com, Scienceline.org, Gawker, Chemical Engineering magazine, and elsewhere. The documents I seek concerns U.S. government operations and activities. Their disclosure is likely to contribute to understanding of these operations or activities.

The requested documents will be made available to the general public, and this request is not being made for commercial purposes.

In the event that there are fees, I would be grateful if you would inform me of the total charges in advance of fulfilling my request. I would prefer the request filled electronically, by e-mail attachment if available or CD-ROM if not.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 20 business days, as the statute requires.
