About 20 minutes later, we got another call that the hot line in the ops tent wasn't work; this time, there was more frustration in the caller's voice. So, I went over and checked out the phone...only to find that the phone had been disconnected from the wires and thrown across the tent. Fortunately, the phones are "ruggedized", meaning that they are intended to take some level of punishment. I got the phone reconnected, checked to ensure that the batteries hadn't been tampered with, and picked up the handset...only to have the line answered on the second ring. I spoke with the person on the other end, explaining the "issue" we'd experienced at our unit, and found that there was only one person manning the other end of the hot line that night, and that they'd gone for a bathroom break, stopped on their way back to get a cup of coffee, gotten into a conversation while they were out, and had only recently returned to the tent.
