I used to take over a hundred flights a year for nearly 10 years, and must have taken close to a thousand flights in my life. These things happen, but more planes run safely than crash. It's just when they do crash it makes more of a mess. I don't think it's on the increase at all - it might just be reported more though.
There's only been about 15-20 or so "big" crashes over the past 10 years really, and the number of people killed on the road each year probably amounts to more than that total. Yes it's horrid etc... but the only reason it makes news is because a plane tends to make a bigger impression on people when/if it crashes.
