There are many cases of PP helping with flight safety as a result of a discussion regarding an accident. I gained a lot for the discussion following the 2007 fatal collision near Abbots Bromley. This thread inspired me to change my operating procedures and has undoubtedly reduced my chances of having a mid air. Other threads have rammed home the importance of “don’t stall” if you have engine failure, again following several engine failure accidents, which were debated, on this forum in some detail.
If you look up the case of the modified micro which crashed on an instructional flight (G-STYX) and killed two people. The forums disagreed so strongly with the AAIB that an alternative report was produced and eventually accepted buy the coroner, although the AAIB has still not formally apologised for its incompetence on that occasion.
