There sure have been a lot of stories of people saying the straps failed on them. Seems like that was a regular occurrence on that ride.
Honestly, I was planning on riding it next month. It looked like a fun ride and I heard a lot of people that thought it was a blast.
I've talked to several people that rode it. They weigh you at the bottom of the stairs and then at the top and regularly turned people away. I'm not sure if it was negligence by the person running it at the time or not, but it didn't sound like the weight was something they "let slide" with regularity.
The straps are another thing altogether. My nieces (13 and 12) rode it the weekend prior to the accident and said the straps were confusing and had duct tape on them. They also said that the person running the ride didn't test the straps to make sure they were secure. She just gave them a "You good?" and a thumbs up (fairly typical of ride operators IMO).
A friend of mine commented that during the second drop, she didn't think her butt was hardly in the seat at all. The straps were the only thing holding her in. She's probably 125-130lbs.
