This tragedy is powerful and I appreciate being able to read of it when is still so visceral and painful for those who were there or affected by it.
It shows the extraordinary power of the internet and a forum such as this to make connections that no other media or method could, and help resolve important things.

A historical case from Australia in 1936 bears a resemblance, in a civil court case for a military officer who struck spectators at an airshow, by allegedly attempting to impress with a prolonged, low takeoff :

In this case the officer was tried for manslaughter but acquitted. A valid function of the justice system is giving victims the chance to express how they are affected by something, to have the system acknowledge an injustice, even if it cannot be ultimately proven.

The coroner in this case…..no Quincy ME.
