Keep in mind the MOST IMPORTANT requirement is to walk away from the helicopter with a minimum of damage to the passengers and crew, as possible. Nothing else matters. Even if they have to recover the machine with a stick and a spoon. As long as everyone on board came away with their body parts and senses reasonably intact, then you are ahead of the game. Cause Larry Bell, Igor Sikorsky or Pierre What's his name can always build you a new one.
