If anyone is interested, MSO will be conducting a mock aircraft disaster on Saturday, May 10 2008 from 8:30AM to 3:30PM Mountain time. This will be a multi-agency simulation with people playing the parts of victims, etc. You may be able to listen to some of it on the MSO feed. Not sure if you'll be able to hear all the ground chatter, but you might hear some of the communications from the tower.
