That may well be one thing that’s wrong, but I’m going to guess that normally, one still wouldn’t have a regional jet flying directly over a helicopter with just 150 feet of vertical separation.
EDIT: I was waiting to see if VASAviation – a YouTube channel that puts up ATC radio recordings – would put up logs for this one. Looks like they have; three separate videos.
