In days of yore, when real discs were still the means of puchasing recorded music, the following was in vogue:
"Ladies and Gentlemen welcome to filght xxxx to yyyy. We are now at 27000 feet in the cruise and you may be interested to learn that you have all participated in the making of history. This is because you are the first passengers on the first ever commercial flight where the aircraft is being controlled totally automatically. In fact there is no pilot whatsoever on board. There is however no need to worry as all systems have been extremely carefully tested and there is no possibility whatsoever that anything can possibly go wrong.....tsk......go wrong ....tsk....go wrong....tsk.....go wrong.....tsk....go wrong (e.t.c)"
