These were scattered after the 1hr 2min mark of the video.

To summarize as best as I remember:

Field said there were surveillance cameras around JFK Jr's plane in its hangar. They recorded someone surreptitiously entering the hangar and placing plastic explosive around the tail of the plane, along with a barometric detonator, which would have blown the tail off the plane during descent.

As a result of this, the plan to fake JFK Jr's death was formulated. The detonator was replaced with a remote-controlled detonator. The Kennedys and the sister-in-law were not in fact on the plane. It was piloted by a Navy Seal with a parachute and a recorder with JFK Jr's voice to play for the tower at the destination. The Seal jumped during descent, and the detonator was activated.

In the side-scroll chat attached to the video, one commenter opined that the three subsequently lived in seclusion on a Greek island once owned by Aristotle Onassis.

There is of course no confirmation for any of this.

Later Field said he was sure Trump's new running mate would be announced on Thursday at the Dallas rally. He did not specify who he thought that was. At one point early on he did say wouldn't it be great if it was JFK Jr, or words to that effect.
