I can't recall the person who made this quote or the exact words of the quote itself, but it is one that I always kept in the back of my mind when flying VFR.
The quote from an air safety investigator (nationality unknown) went something like this when commenting on aircraft accidents involving inadvertent VFR flight into IMC:
"It amazes me that the day following an aircraft accident is invariably always a sunny clear day"
Maybe somebody can source and post the exact quote because it is a good one for VFR pilots to remember when making go/no go decisions (and for clarification I'm not relating this quote as necessarily being the cause of the current accident situation. Other more qualified people than I will make that determination).
