Francis Scott Key Bridge collapse in Baltimore...

OK, I was assuming the ship called CG based on my past experiences but we'll see once it all shakes out. If they (state of MD, port of Baltimore, whomever) were able to shut down traffic on the bridge in under 5 minutes from the ship losing power that's truly amazing.
The pilot would be in communication with vessel traffic control/port control. Mayday would be the first communication to USCG.
