Should we be worried about death from the sky?

A couple of weeks ago, a 30-foot-long rocky meteor exploded over Indonesia. The force of the explosion is estimated to have been equivalent 3 Hiroshima-type nuclear bombs. Oooo. Scary.

Of course, it exploded high, high above Earth and no damage was reported. And such rocks only cross our paths every few years.

Even so, the article plays up fears that something bigger and worse could smack into the planet at any given time. A sophisticated network of telescopes would be needed to spot rocks this small before they get close to us. Is it worth the investment? I have no idea, depends on how worried you are, I guess.
