...and let the NTSB get on and complete what will no doubt be a very difficult job under the circumstances.
It will be interesting to see how much effort the NTSB put in
With little evidence (?), a light single and just a single fatality, it is a regrettably common GA accident
The "unusual" aspect is how well known the fatality was... and I am not sure that is grounds for a much deeper than usual investigation?
