So, what happens if there's a fire in the TRACON and they're required to evacuate? What happens to all the aircraft? I can just see the look on the pilots' faces...
"Whatever Tower, Cool Airlines 100 on ILS 26L with you..."
"Whatever Tower, Cool Airlines 100 on ILS for 26L with you.... are you there?"
"Cool Airlines 100 to Whatever Tower, are you there?!"
....
"Whatever Approach, Cool Airlines 100 - on ILS for 26L, I can't get any response from Tower on 118.0"
"...Approach, are you there?"
"Hello? ANYBODY?!"
Um... so what happens when there's an evacuation? Who takes over?
