How about spending some time, money, and angst on an AOA instrument?



But the thread is about glider-to-glider mid air collisions. And the statistics support the idea that an auto accident on the way to the airfield is more probable than a mid air collision once there. Again, no one here is suggesting that soaring is not dangerous (certainly not me), just that mid air collisions in general and glider-to-glider mid air collisions in particular are a negligible part of that danger. 99% of the fatalities are collisions with terrain - not involving other aircraft. Flarm could eliminate the remaining 1%, but soaring will not be much safer as a result.
