Anyone know if this is pure co-incidence or a design fault? I also disagree with the idea that this is not a safety critical incident:
'It is of course a serious issue when something falls off a helicopter during flight, but neither incident presented any critical risk to the safety of the aircraft or the passengers. A window falling out does not present any danger to life as a helicopter cabin is not pressurised.' 
So it's serious and not....!
