More B.S. !!
How many of those reported near misses were with nether aircraft talking to ATC or within radar coverage?
Granted the accident at Minden described in the article was tragic and gladly no loss of life, and within radar coverage.

But that would not help in our valley this weekend with a guest P-51 Commemorative Air Force from a nearby airport giving rides in our valley, low level, below radar coverage, fast, not on the frequency, with gliders around. low level to the point that he had to climb to clear the ridge with gliders on the ridge above him.

Unless he has TCAS on board, he would not have seen a gliders transponder, and he was below ATC coverage.

Half of the gliders aloft in the valley had a transponder.
