IMO from the park's point of view a Velcro failure would be the best possible outcome for them. If it was a mechanical or engineering issue then I could see the park not being able to recover, but if they can blame it on the straps then all they have to do is replace the restraints and then market the ride as safer. Look at the accidents revolving around The Smiler and Texas Giant when the incidents first happened there was a lot of negative publicity, but over time things are going back to normal and the parks are recovering.
I too was only trying to point out that there were other reasons for the nets; because, if the only reason for the nets is to catch flying rafts then it will hurt the industry as a whole. The way the general public is they will say if the parks feel that way about those types of rides then are we really safe on the other rides as well. That line of thinking would then cause people not to go to parks and then hurt the bottom line.
I don't think the owner was particularly proud of the rafts going flying I think they were trying to show why they had to delay the opening of the ride, and show how they have made the ride safer.
