I was working on Kwajalein Atoll in the Marshall Islands in 1993. A couple of "rocket scientists" were secretly doing dives in the mid 300s range with basic sport diving gear. They thought the current air record in the high 500s was not much of a leap from what they were doing, so built plywood backplates to hold 4 tanks and regs, and went for the record, even though, living on an Army base and under Army rules, they could tell no one. One guy watched his buddy convulse and drown at depth, then rocketed to the surface, living long enough to say"my buddy's dead" before his eyeballs started fizzing. The other diver's body was never found. A secret logbook was found in their room detailing their workup dives and intentions.

I had already tried using google, and also archive.org. Maybe I missed something, but thanks anyway.

Plywood backplates... that's interesting idea.

In 1959 three Italian divers (Olgiai, Novelli and Falco) reached a respectable depth of 130 meters, or 426,509 ft. with compressed air scuba.
A new type of regulator was designed for the occasion, the Pirelli "Explorer":

Double Hose Regulators - Pirelli

the designer was one of the three, Dr. Alberto Novelli, who ironically was the first to go down, but forgot to make the hole in the plate placed at that depth, losing the opportunity to prove that he had gone down and had reached the depth......
So the record was officially registered only in the name of Olgiai and Falco.
