This paper contains nothing new to airline people. It is not an original contribution. For some time I had been under the impression that the ideas we use and the troubles we have in the airline business were clearly understood by technical people outside the airlines. Recently, however, I have been surprised to discover that this is not so and this fact is the excuse for the shape of this lecture. So I am not talking to airline people but for them. If, when you have heard me, you have heard nothing you did not know, I shall be happy.
