I am hearing multiple comms on freq. 154.16 in my Berlin home right now at 2049 hrs. Its been going on for about an hour now. It sounds like a command officer receiving multiple mayday calls. Some happen in succession. Then I didnt hear it for a while, now I hear it about every five minutes. Some say firefighter down. One was for a firefighter tangled in hoseline. One was for a firefighter tangled in wires. Each time I hear RIT team responding. I also heard there was multiple structure collapses. I hear a Ladder 1, and F 18. I am unsure where it is coming from or if it is a drill. Anyone have some info.
