I was quoting—I hope accurately—Mr. Justice Major's inquiry into the Air India disaster of 1982. In that, looking at various aspects of aviation security, on one hand he noted that there has been no conclusive proof up till now that this constant and intense scrutinizing of passenger name information against watch lists has prevented further airplane disasters. On the other hand, he called for increased screening of baggage, cargo, cargo planes, non-commercial flights, areas around airports, airport personnel, and so on. It was in that context that I was quoting the Major inquiry.
