I was struck by a comment you made on page 2 of your presentation. You said that it is unrealistic to think we can eliminate 100% of the threats in civil aviation, and that such screening would, in fact, “encumber the air transport network to the point of paralyzing it”.
What do you think it would cost if the Canadian airline civil aviation system were to shut down for a week--post 9/11, for example--if an incident were to occur in Canada? How much would it cost?
