Mid air collisions are dramatic events what with fireballs and flaming
debris falling from the sky. Fixing the problem involves some cool
technology too. The whole thing tends to get folks excited.

However, the sad statistics say that a midair is one of the least
likely ways to die in an aircraft. The most frequent fatal glider
accident is just hitting something while you're trying to land -
fences, trees, etc.... It's the leading type of fatal glider
accident. Miss-handling a takeoff roll or a premature termination of
tow is the 2nd leading cause. Neither are as dramatic, but they're
far more lethal. The fix is just mundane stick and rudder skills -
not gee whiz technological solutions.

Folks, please be careful out there.
