Ric Gillespie has a site for his organization, The International Group for Historic Aircraft Recovery, which includes a forum (it's a small community so I'm not going to link directly). If you're interested in aircraft, it seems like a good rabbit hole.
A couple weeks ago he posted an update on an artifact found at Gull Pond in 1992:
...TIGHAR Artifact 1-21-P-1 can now be reliably identified as a segment of a cylinder wall from a liquid-cooled internal combustion engine that pre-dated the first use of machines of any kind on the Cape Shore barrens...
The materials, properties, and dimensions of the artifact match a specific section of a cylinder from a 450 hp Lorraine Dietrich W12 engine like the one that powered l’Oiseau Blanc.
The disc found during the filming of the show still hasn't been identified.
Two more interesting tidbits: EU paid for the magnetometry scan. However, ultimately it might not have been helpful. Again from Ric:
The survey was flown with the sensor 5 meters over the water surface and the transects were 5 meters apart. That's not tight enough to see something as small as an engine in a magnetic environment that active...
The bottom line is magnetometry is just not a good way to search that pond. Sonar is not practical because the pond is too shallow. It's down to Mark One Eyeball and hand-held pulse induction metal detectors.
