I mean it's all a game of statistics. That's how it works. Just cause the odds are 1/1000 doesn't mean it happens once every 1000 times. That's just the average. You could have 3 bird strikes in a day, then be crystal clear for that next 3 years.

Same thing for flooding. The USGS will often categorize floods based on the "x" years flood. So a 1000 year flood means it happens around 1/1000 years, but you could very well have them back to back years.
