Great play on Title wording
Anytime that you have more than 5 minutes between accidents than one could argure that Air accidents are at their all time low of zero in-between accidents
On the other hand if one considers that both pro-active and re-active preventive measures take years to implement and generate meaningful statistical effect than maybe a 5 year rolling average rate might be a more realistic measure, although it makes a lousy headline or grabber thread title
