Federal Aviation Administration division chief for accidents and investigations at the time of JAL Flight 1628 over Alaska in November 1986, and the reason that case has a documentary trail at all.
What he says happened
On his account he assembled the radar data and the voice tapes and briefed a room that included FAA officials, Central Intelligence Agency and other agency representatives, who then told the participants that the meeting had never taken place and left with the material. Callahan says he kept his own copy of the data and the tapes, which is why the case can still be examined.
What that makes it
One of the few cases where a named federal official states, on the record and from a position that would have known, that evidence was collected and the collection was denied. It does not establish what the aircrew saw. It establishes a documented instance of the behaviour the secrecy argument in In Plain Sight is about, from someone with no obvious reason to invent it.
