Dad an MP at time of the "Arrow." Had this Dief-Arrow anecdote about kids meeting PM in his office . 
"Dief stood over by the window and – as usual – picked the two prettiest girls from the group for a photo opportunity. It then became a photo shoot for the Chief and some thirty kids. He then gave a ten minute talk, with the teenagers hanging on every word. When he asked them if they had any questions, they leapt at the opportunity. While this went on for almost forty minutes, somebody kept coming and looking in the door anxiously. Diefenbaker repeatedly waved them away. When we left his office, we could see three men sitting in the anteroom. They were not a happy trio and the one with a rising red face was Crawford Gordon – then the president of AVRO Canada. The decision to cancel the Arrow was vital politically and the biggest news event for a couple of years. Ironically, while those executives were in Ottawa for a crucial meeting, the Chief preferred chatting with high school kids."
