Some years ago when involved in airspace liaison, I used to frequently drive from Sydney to Canberra for meetings with the [then] CAA.
The ATCO's with whom I was working gave me a copy of the tape to while away the time on the freeway. Indeed, it gave one something of a reality check considering some of the lofty deals we were pondering at the time!!
It's obviously as relevan today as then.
