I really doubt that there is much difference at all in the number of passengers killed, injured, or even inconvenienced by hijackers on planes today compared to the 80's. There have only been a handful of significant incidents in the past 30 years, and probably half of them occured on 9/11. In contrast, air travel has become horribly inconvenient for almost everyone due to the security theater. We have nonsense restrictions, much longer wait times to get to our gates, and invasive sexual assualt security checkpoints. We've given up far too much for little or no benefit.
