Hmmm let's see. As far as I can recall I have had 4-5 outer pane failures in 3 different types of aircraft. None precluded me from continuing the flight to destination, however on 2 occasions I was leaving home base, and Maintenance wanted me back exactly for the reason that they had a window, whereas availability at outstation was either questionable or definitely non-existent. On the other occasions landed at destination and gave the airplane to Maintenance.
Non-events, except for a slightly extended layover at an outstation a couple of times.
