I have mentioned in this space before that I have the opportunity to travel a lot and that this has afforded me an excellent view into how airports are run. But my perspective is not limited to their inner workings. In fact, from my office here in Montreal, I can see the O6L and 24R runways at the P.E. Trudeau airport. This means that, every once in a while, I get to watch these feats of engineering and technology move through the air. And I am reminded of the incredible precision required to get so many planes safely through take-off and landing every day. At the same time, I also know that any disruption on the airfield —no matter how small— can delay flights or threaten security.
