The Torness nuclear reactor is relatively close (within 20 miles or so ) of our family home. Therefore this article is of interest, especially since they mention an incident in April 2003 where a jet flew so close to these reactors that intruder alarms were activated.
However ... I wonder the actual probability of a jet aircraft actually hitting a particular spot--the spot being a nuclear power plant. They rarely crash. Yes, it happens. I fully support efforts to enforce "no-fly" zones around nuclear reactors, but I can't help but think that occasional breaches of this policy are not as important to manage than other risks associated with nuclear power plants.
