Lots of lessons to be learnt from this tragic accident. Pressures of private flying, especially with kids, wives and mates... I didn't realise how challenging it was until I got out of commercial flying recently. Flew quite a bit years ago before I got my commercial licence with family and mates, however now having experience I must admit that I was very naieve back then given some of the flying that I done, especially over Bass Strait back in the late 80s.
Most flying schools don't address the potential human factors issues that private pilots may be faced once they get their PPL.
