I think that the feed was just not up. I initially got to the feed about 1hr after the accident and there was no feed for the previous 6 or so hours. Presume that the feed was just down. Would need Squak7700 to confirm.
Relevant transmissions would be a few minutes before the 2200 feed starts.
Also not sure what freq's the feed covers. I don't believe Essendon departures are on the feed anyway.
