It reminds me of the famous radio programme by HGW.

Thanks jmh for the reminder. I live near the area where HGW set his play(?) and one night when I drove out of a suprmarket's parking lot, I turned on NPR and they had that show on (marking its anniversary). I came on in the middle of it and thought it was for real and wondered why there was no panic on the roadways.
