Then you're looking at the wrong news!
http://www.avherald.com/ is a good place to start to see what really happens around the world. The vast majority of "emergencies" end well and at most end up being reported somewhere like AVHerald or here - not on mainstream news.
Remember, there's around 100,000 scheduled flights per day around the world. "Several" emergencies per week is noise (and probably far fewer 7700's than there actually are).
