I feel very strongly about that. One of the world's leading accident investigators and aviation experts, Dr. W.O. Miller, who was a special expert to my commission at the conclusion of the Dryden inquiry, is, I might mention, the former chairman of the Accident Investigation Bureau of the National Transportation Safety Board of the United States. He's an aeronautical engineer, a university professor, and one of the world's most respected aviation accident investigators and aviation safety consultants. After the conclusion of our commission, he stated to me in writing that from his experience with our inquiry, he felt every nation should test the safety of its aviation system every ten years or so with a major inquiry similar to the Dryden inquiry to check its vital signs.
