I've worked with Funtastic Shows for many years when I was younger. Traveled many cities with them, even knew Burback in Salem when he was a kid. One thing for sure, three people in the gondola cannot, repeat CANNOT turn the gondola upside down. Its just not possible. Gravity will allow it to swing up to about the 9 and 3 positions if thinking of it like a clock, but that's it. And you would need to be strong and in perfect sync with the others in your car to get it that far. As one who traveled in several carnivals, trust me we tried it all. Yes you could fall out at those positions but that's not what happened here. in one of the early photos the newspaper printed you could clearly see the door open. If the door was not latched correctly it could easily lock with the main frame of the ferris wheel causing the gondola to lock in any position which would then do a complete 360 at some point during the spin. Sorry but taking selfies did not cause this problem.
