EDIT: The link covers an incident where one of FRA's planes were shot down in 1952. Everything were successfully covered up for more than 50 years, and a lot of the reports are still unavailable. The FRA _really_ likes to not talk about themselves, more so than many other intelligence agencies.
The FRA claims that the now 65 year old reports could still pose a threat to current operations.
And it is really hard for journalists to write something constructive about the FRA because of the secrecy [1].
