From Air Force Times:
Air Force officials said Dec. 5 that the service’s policy for publicly releasing documents is applied narrowly enough not to conflict with federal law.
In a series of email exchanges, the Air Force had previously seemed to indicate that it applied the policy, which requires documents to be released only in PDF format, to all information requests, including those made under the Freedom of Information Act, or FOIA. That law requires federal agencies to release documents in any format requested, with a few exceptions.
