I knew Eric well and am deeply saddened by these events. As an airline pilot of some reasonable experience my aviation mid life crisis was to take a ppl (h) course. This took 7 years to complete part time probably a) because I was fairly useless and b) the eye watering expense. Hugely enjoyable, though and I finished in 2014.Ironically, Eric was one of my subject matter experts I phoned for all matters, rotary. The point that I will make that even with my experience as a professional fixed wing pilot, my initial embarrassingly ham- fisted attempts to control the R22, exponentially in the hover would in my view, make it unlikely that Isabella sitting in the other seat could really assist in a catastrophic event assuming she really had no official helicopter qualifications. Anyway, RIP to all.
