I don't know how we could find the insurance information (without expending a lot more in time and resources than any of us here have).
I notice it merely says that he worked as a tower engineer, so it's possible that he was sort of a free-lancer who was employed on an individual basis by those stations (and hence probably covered by their insurance). In other words, possibly he did not go in his capacity as "working for Prometheus Methods," and hence being a contractor or subcontractor, but simply as an individual.
Prometheus Radio Project seems to have been a registered organization of some sort (a non-profit?) in order to accept those grants. I wonder if the "Methods" group was somehow legally part of the "Project."
I realize it's possible that there's no connection between the two groups - perhaps Berg Sr. just knew about the Prometheus Project and wanted to name his business after it as a sort of tribute. Which is still not a very positive sign!
According to a clerk at Baghdad's Al Fanar Hotel, on the east bank of the Tigris River, Berg checked in on March 22, left for Mosul the next day, returned to the hotel on April 6 and checked out on April 10.Berg said he was going home, the clerk said, and walked down Saddoun Street, a major artery, because the road was closed to vehicular traffic. He left behind in his room a yellowed and folded page from a book by Jon Burmeister, a South African writer of thrillers who died in 2001.
The page carries a short prose poem titled "The War That Wasn't." It describes a man named Jericho, who is awakened by machine-gun fire, "his heart hammering thunderously against the ribcage as though trying to escape."
The poem ends: "What the hell was happening? God knows, he thought. But it seemed clear that the war had arrived -- the war that wasn't coming here . . ."
