It is very good news that no one was hurt in this unfortunate incident. I do wonder why all contributors so far have taken this so lightly, as if it is a natural and regular occurence. Please tell me I am mistaken. I can just imagine the uproar if this had happened in the States. How can this uncommanded release happen? Equipment failure, crew failure etc? Serious question and not directed at this incident which someone rightly said will be properly dealt with by a BoI.
