I too am against any mandated surveillance. We can help by voluntarily recording flight info. If we survive a flight (ugh, better choice of words?) we can maintain privacy by erasing the recording(s), if unlucky, they may solve the cause and save lives.

The problem is that recorders we can readily use will likely not produce a recording that will survive an accident. We need data storage that will endure extreme Gs including shock, smashing against rocks after plummeting, becoming wet for a long time, and scorching in a hot fire. Would creating a glider black box lead to usage mandates?

Yes, please log GPS 1/second or faster if possible.

I don't use PowerFlarm because almost all of my close calls were with powered civilian an military aircraft, and would have done no good. We need a truly universal solution.
