It was Bernard Shaw, John Holliman, and Peter Arnett. I'm quite sure that Holliman and Arnett were reporters, not editors.
Shaw retired from CNN a few years ago, but very occasionally has been known to reappear. He was actually doing a phone two-way not so long ago, when the White House was evacuated and he was in the area. He phoned into CNN and did one of the first reports.
Holliman was still working for CNN when he died in a car accident in the mid-late 90s, and was one of their top correspondents.
Arnett worked for CNN until, I think 1998, and the 'Operation Tailwind' special that CNN broadcast, about the US use of nerve gas in the Vietnam war. CNN put the programme out, it caused an absolute storm, the Pentagon denied all knowledge, fired all sorts of comments at Arnett and CNN, and the idiots in Atlanta decided to back down and withdraw the story. They sacked the producer of the programme, and Arnett was kept on but never given any assignments, so quit.
It transpired, a few years later, that the CNN report was in fact entirely accurate.
Arnett was working for MSNBC/National Geographic in the last Iraq war, then went on Iraqi telly to say that America was fighting a bad war, so NBC sacked him. Not sure what he's doing now.
I'm pretty sure that's all accurate -- it's all from my memory!
