I recall that the Italian prototype crash involved a rotor brake fire that caused the carbon-fibre control runs to lose integrity - something that occurs in that type of composite at >300deg C. Thereafter the control runs were re-engineered in metal.
Agree with the sentiments about not second-guessing the BoI. At least there appears to have been uniformity of action regarding suspension of normal flying - more than can be said of the Lynx Mk7 after one shed a main-rotor blade killing two friends. After that tragedy, the army had a shambolic lack of leadership and policy, with some grounded in front-line units, while others (both training and operational) continued to fly.
Hope the crew in Cornwall are recovering well.
PS: Didn't Wastelands test crews step out of one on the ground following an ACSR failure a few years back?
