Whatever the reasons for the actual crash, it appears that the public at large and the famlies involved will understand that this flight took place whilst Mr McRae was not current on type. Unfortunately, the AAIB investigation shows that this does not seem like a "one-off" which can be put down to oversight as there is a history of Mr McRae flying whilst non-current.
The McRae legal team are putting a brave face on it but I think any PPL, fixed or rotary, will be disappointed and saddened by this story.
