What you are looking for, is a statistic based on commercial aircraft, in contrast to johnables answer. Here is a complete list of commercial accidents - every commercial flight accident ever. Yes, there has been so few: http://en.wikipedia.org/wiki/List_of_accidents_and_incidents_involving_commercial_aircraft To make it all even better, this is accidents, not crashes, meaning that even though an accident is listed, it doesn't mean there was any injuries. Also, there has been a total of 0 commercial crashes in the USA, the past 3 years. (maybe more, didn't bother to read any further ;)). To sum it all up - the chances are incredibly small!
