JFK Assassination: Fully restored Air Force One recordings from November 22, 1963

Tuesday, November 19th, 2013

John F Kennedy At the end of this blog post is a fully restored digital audio file available for listening and downloading of the government conversation that occurred at the time of the assassination of President John F. Kennedy. The Announcer at the beginning of the recording  is the poorest quality of the entire 2:01:59.

This is a combination merged from two copies that were in existence. The first copy was released by the government and referred to as the ‘LBJ tapes’ in the early 1970’s. Another longer copy surfaced in a Philadelphia private auction in 2011. This longer copy was found in the belongings of the late General Clifton. Thanks to Bill Kelly, a veteran JFK researcher, Primeau Forensics has combined the contents of both recordings and fully restored them.

In this enhanced recording, you will hear conversations from Air Force One over the Pacific Ocean as they abort a trip to Japan and turn around, mid-air, to return to the mainland after learning about the assassination of the President of the United States. These recorded conversations between Ground Command, the White House and Air Force One include code names such as ‘Duplex,’ ‘Digest,’ ‘Volunteer,’ ‘Liberty,’ ‘Witness,’ ‘Crown,’ ‘Baker,’ ‘Watchman,’ and ‘Tiger.’

During the call they make arrangements to transport John F. Kennedy’s body, his widow, President Johnson and the other 40 people safely back to Washington DC. The carefully coordinated and strategically executed planning is heard in this recording. Decisions about media coordination on the ground at the White House, the post-mortem autopsy to be performed by law and President Johnson’s conversation with JFK’s mother, Rose Kennedy can also be heard.

It may take a while to get your ears acclimated to this early, mobile technology. Primeau Forensics has carefully removed unnecessary radio static and squeals to accommodate better listening. It is recommended that you use a combination of speakers and headphones to best listen to these recordings.

Air Force One Audio Restoration/Enhancement Process

Friday, November 15th, 2013

Air Force OneA lot of people have been asking how I restored the Air Force One radio transmissions from November 22 1963, right after JFK was shot. Below I have outlined my process with brief explanations about each.

I used a software program from Adobe CS 6 ‘Audition’ for this entire process.

I identified the points in each version of the tape recordings, the LBJ version and the General Clifton version, for edit points before altering the recordings for enhancement.

I began the restoration process by sampling the tape hiss present on the entire recording and reducing with Adobe noise reduction. Next I went section by section and reduced the radio transmission noise which varied from conversation to conversation.

Then I applied equalization and compression filtering to help bring out the conversations. This was also done section by section since each conversation varied in speaking frequencies.  Adobe CS6 has a great tool, the FFT equalization which is very easy to use.

Audio restoration and enhancement is a process. I refer to it as peeling an onion; one layer at a time. If something does not sound right, I go back a step and try a different process. That’s the beauty of digital audio restoration and enhancement.

I am still working on the restoration as time permits and will update the videos posted here. I am hearing more and more of the conversations using critical listening and additional enhancement. Considering how primitive the technology was back then I am very impressed with the sound quality of these recordings. By the way, the General Clifton version is much better sounding and longer then the LBJ version.

Primeau Forensics Restored Air Force One Recordings from John F. Kennedy Assassination

Tuesday, October 8th, 2013




Passing the Torch-An International Symposium on the 50th Anniversary of the Assassination of President John F. Kennedy will be happening October 17-19 2013 in Pittsburgh. http://www.duq.edu/events/jfk

A while back, Bill Kelly contacted Primeau Forensics and asked Audio Forensic Expert Ed Primeau to assemble and restore the original Air Force One radio transmissions that were recorded the day JFK was assassinated 50 years ago.

According to Primeau, ‘the quality of technology back then was very poor which weighs heavy on understanding the dialogue of the radio transmissions even after restoration’. Then Primeau had an idea, to have Partner Company Primeau Productions create a video which displays the wording on the bottom of the screen displaying the dialogue from the radio transmissions as they occurred.

Primeau sought some authentic footage from a private jet cockpit via a pilot who is a friend of Primeau Productions so the background footage adds an interesting background to the closed caption type text.
