This might be of interest... I think it's implied that the Egg Harbor guy worked at Braniff International Airlines from April 1965 to July 1965... resigned for "personal reasons", but there's another possible reason (?) redacted. I am pretty sure it's the guy because the timeline matches up with his employment records from the last 302s as well as mentioning the same field group.
Might be more about this guy in there, it's so redacted it's hard to know who is being talked about though, I was just able to make the connection here because of luck.
*I confused United Airlines and Braniff International Airlines, the EHS guy seems to have worked for the latter - my bad entirely.
