Jeremy, there are a couple of inaccuracies with the material you posted. First of all, the seat belts on Holiday World's rides, including the Raven, are not aircraft-style #800 buckles as are frequently seen on PTC trains, but rather push-button automotive type buckles (that aren't generally used much in automobiles anymore since the auto industry switched to end-release buckles) which are less succeptible to inadvertent release.
Second, part of the reason for fastening the belt around the lap bar is that there is nothing under the seat cushion in the back seat of a PTC articulated car except the car's rear axle. If the belt falls down between the bench and back cushion, it lands on the track assuming it doesn't get caught under the road wheel first. I suspect that this may be the reason PTC uses those big clunky aircraft-style buckles; the buckles Holiday World uses are much nicer and a lot more comfortable, not to mention easier to fasten and harder to unfasten. They're also much thinner and could easily slide down between cushions.
Third, in response to your question...
On every ride I took on Raven and The Legend last weekend, an operator physically tugged on my seat belt. This appeared to be standard practice...a mechanical inspection of every seat belt on every dispatch.
I see Jeff understands my point. For practical purposes (though it would be very difficult to meet engineering standards...proving a negative again) if you put an unrestrained person in a normal seated position in the train and it consistently comes back to the station, you can have some degree of confidence (probably related to the number of successful trips) that the condition is 'safe'.
From an engineering perspective, a better test would be to place a 'body' in the seat in a standing position and see what happens. Does that "rider" still come back every time?
The challenge is not only to identify a 'safe' condition, but also to identify an 'unsafe' one. Identifying things that did not fail doesn't tell you what happened.

Also, I think it should be noted that the release buttons on the seatbelts are slightly recessed.
As for witnesses, I agree it would be extremely difficult for anyone in the train (except for her riding partner) to notice her "standing" in the ride. But keep in mind there are also others who are in the restricted areas. I recall a conversation on Friday evening where someone from last year's SRM noticed while on the walk back that someone was indeed standing in the coaster and alerted the appropriate staff. Personally, I feel there are some people who like to push the limits.
Being a lighter person, I find that I tend to come off my seat a great deal. I'm careful about keeping my seatbelt tighter because of this (goes back to the days when there were no seatbelts and buzz bars...I just feel safer with the seatbelts). I have no doubt if I didn't have my seatbelt tightened sufficiently, I would become airborne enough to hit the lapbar. And this woman was 30 pounds lighter than I am.

I was riding Timbers shortly before the incident at HW. My belt was always checked (and tightened at least once), as was the lapbar. I have a feeling that HW was NOT at fault for this accident, as they were doing the same safety procedures.
What the rider does after entering the lift hill is beyond anyone's control. Except the rider.

Dave are we talking about highbacks?
Chuck, who was thinking just that when the standing position was mentioned and in ravens case even with those restraints, Standing might not have been intentional.
Chuck, accepting the fact that improper practices were probably a significant cause but may not be the total reason.

"[Tony] Rossi stated a person who is sitting correctly in a roller coaster seat--with backside down on the seat and feet on the floor of the car--would not come out during a ride, even if that person were not holding on."
"Rossi's inspection will include a review of all Raven maintenance records and every inspection record. Engineers will be on hand Friday to assist in "test dummy" testing of the ride, as part of the inspection process."

Sorry, I may be speculating again. But, so were those who said a piece of foam wouldn't hurt the Space Shuttle.

Just hopeful that Holiday World will bounce back as quick as humanly possible, and that the staff and extended family heals reasonably.

As far as adding a second train to the Raven, I doubt that will happen as the ride is over to quickly to effectively unload and reload another train. However, the park may decide otherwise in the future.

As for a second train...
With Holiday World's normal operations, a second train would make a difference because while it is a very short ride, it takes longer to load than it does to run it. It would be a bit like the two trains on Mr. Freeze. It would stack all the time, but the overall cycle time would be reduced, resulting in a capacity improvement.
As a general rule, a second train will almost always increase capacity even if it always stacks, because you're eliminating 'down time' in the station. It's when you talk about adding even more units (impossible on the Holiday World coasters) that stacking and double-stacking may eliminate the benefits of additional units.

I believe the Knott's Berry farms' operation procedure will come into play after this incident, at least to the point of riding with your lap bar down normally. One click-two click procedure may be thrown out for a while, not by just the parks but also us, the enthusiasts.
I've come to realize that safety is a very relative thing when it comes to amusement rides. I mean it's clear that the Raven is "safe" already as it has had thousands of riders on it who have not been hurt. And they've already declared that the restraints were functioning properly. On the other hand, could this happen again? It's conceivable.
Then there's the Matterhorn at DL. It has had several deaths. One a definite stand up situation, and the other I'm not sure they ever found the reason. Yet the ride still runs today with rider defeatable seatbelts as the only restraint. And though it has had recent modifications, you could still stand up on it and be killed. Yet despite these incidents, and the potential for more, the ride is declared safe and runs pretty much as it always has.
After thinking about these situations, I've come to the conclusion that more needs to be done. I just find it strange that parks would be comfortable with restraints that can be rider defeated. It puts them at risk for higher insurance cost, lawsuits and can take a popular ride out of action for weeks or months resulting in lost revenue.
I hear comments like "parks can't protect people from themeselves" and while that is true to some extent, having something rider defeatable...well... defeats the purpose of restraining in the first place doesn't it?
Would it be expensive to modify trains with a restraint that riders couldn't mess with? Yeah, probably. But how much value do you put on one (or more) life? And if you are a park owner, how much value would there be in a system that prevents incidents that give your park negative publicity and possiblly legal issues to contend with? Not to mention the emotional issues that arise after a death in your park.
Something for people to think about.
