What Really Happened on Bullet Coaster October 27th 2023?

On October 27th 2023 at Happy Valley Shenzhen Bullet Coaster was operating normally. The ride was running with 2 trains. Train #1 was launched, but partway through the launch a fault occurred that caused the launch to be aborted. The train rolled partway up the first hill, but rolled backwards due to the launch being aborted. The ride fell backwards down the first hill. It then collided with the, still unloading, train 2 in the station, sending it flying backwards out of the station.

Until management starts seeing jail time for cutting corners, this is going to continue to happen.

[@tikimillie]

And knowing capitalism, im not risking it, no matter how small the chance of an accident may be

[@electric_claire]

It sounds like the managers here *are* being criminally charged.

[@smilesgirl17]

Management? Mmm…try CEO

[@AnotherSwissYoutubeUser]

It's always the same causes >Ride needs repair >Park gets repair but in the cheap way >Cheap maintenance works for the moment but will fail later on >Accident happened because cheap maintenance didn't fix all the issues Money and greedy people (higher ups) not wanting to invest it happened multiple times before.

[@UwePieper]

Ah... human stupidity is another cause that happens quite often.

As a ride operator, I love watching your videos. They're even more encouragement to complete my safety checks thouroughly and help me to better train operators on disaster prevention

[@Bowling_Dude]

I don't understand how any ride op wouldn't have this attitude. I know if I was a ride op i'm being overly cautious towards everything related to safty. I don't need a guest being injured or killed on my mind if it was something I could have prevented.

[@mgloven9533]

@BowlingDudeTTV In my experience, most ride ops know they have to do safety checks every day, but some operators dont understand why we are required to test so many small things. I like to use these incidents to help them understand the importance of every detail and being thorough every single day.

this shows that cutting corners will always end up hurting riders, how the hell does this still happen in modern day

[@AceAviations2]

@@BozeboThere are more severe punishments to my knowledge in the U.S. and E.U., particularly when it comes to accidents this bad. So there is more to lose by cutting corners in this way for the park, sadly that isn't the case in China.

[@keiyakins]

I'm impressed with how quickly Shenzhen managed to get out a thorough report. It doesn't sound like they rushed it either, just didn't let it drag out.

[@CoasterCollege]

They did a really good job with the entire situation imo

[@lward53]

I do appreciate that the contractor that was hired, did point out that the repairs needed to be done, but whats interesting to me is that it was allowed to turn back on with expired parts. But as is almost always the case, Money was the direct cause of this accident.

[@eliza_tu]

Knowing absolutely nothing about rollercoasters, I appreciate the clear, straightforward explanation and animation! Keep up the good work!

You are so passionate and accurate about roller coasters, I love your channel!

Another excellent analysis! It’s a pleasant surprise that the Chinese government has been relatively open about this incident. They’re usually quite cagey to say the least.

Such a tragedy. My heart goes out to the families of the victims.

Thank you so much!

[@MattRoszak]

I love learning about what went wrong when disasters happen.

[@ancientaccount7982]

One almost wonders if the maintenance employees arriving before rescue workers and taking actions which "coincidentally" deleted technical logs was intentional. With how damaged the coaster was physically from poor maintenance, it wouldn't be surprising at all if there was evidence of digital tampering as well on the operations computer, bypassing hardcoded safeties or the like to ensure that these slapdash fixes would run.

[@Black-Swan-007]

I've been watching your videos for a long time. I saw this pop up in my recommended but did not see it in my sub box. It was then that I realized I hadn't subscribed when I thought I had. I am now!

[@scottduke2809]

criminal charges? wonderful! good to hear that, thank you for such great videos!

[@ArekusaSan]

I’ve never had a fear of roller coasters specifically, because I’ve always known they are highly engineered to provide a safe ride experience. My biggest fear - as proven again in this video - is the people maintaining these coasters cutting corners, neglecting the well-being and life of the people who ride.

[@wolfieeeee256]

Your graphics are awesome man, effort!!

[@CoasterCollege]

Much appreciated!

[@lknanml]

I spent 12 years in Army Aviation as a helicopter engine mechanic. It's the little things that get you. A few tiny mistakes or lax with procedures and practices and those little things add up FAST. Even the quickest job or fastest inspection needs to be done and checked. Bolts are DEADLY when out of place. Even a tiny nut can bring disaster. I've seen helicopter drive shafts cut in two by a bolt that got loose and wedged in and acted like a lathe and just cut the spinning shaft in half. The Army has run into issues with parts now and again. A bolt failed when installing so on the ball mechanics decided others should be tested just in case. Those 3 guys saved lives right then and there. Lower quality bolts with higher quality rating were found. EVERY HELICOPTER that used those bolts had to be checked. Army wide....... The odds of a crash do to failure were high because of how many of those type of bolts were used. Maintenance and inspections save lives every day. No glory. No extra pats on the back. The job needs to get done and done well by the person trained to do it. The proper mindset is that job I just finished was the most crucial task of the day. Rinse repeat.

[@Coyotek4]

I'd like to see a 'WRH' video about the tragedy involving a Reverchon Himalaya ride in Houston TX (which did result in a fatality); I'm pretty sure that accident led to similar flatrides by the same manufacturer to never run backwards since.

Love your work. Amazing video as always with great analysis. I also completely believe an email being ignored. They were well aware of the expiration of the parts, it saddens me that no one bothered to follow up. I work in an office setting, so if I don't set reminders to follow up with people who ignore me, things do get missed. My job doesn't put peoples lives at stake though!

Seeing The News Footage Of The Actual Rollback Gives Me Extreme Chills Knowing What Tragedy Was About To Happen..... My Prayers Go Out To All The Injured Passengers. I Wish Ya'll A Swift Recovery.

[@surtech5]

So, they won the refurbishment contract by lowballing how much it would cost them.... then when they realized they wouldn't make any profit, they just decided not to finish refurbishing it? That cannot be what you're saying... For the love of my dwindling faith in humanity, please tell me I'm misinterpreting.

[@CoasterCollege]

That is essentially what I'm saying.

[@coreythedog645]

It’s worth noting that ALL S&S Air Launch Coasters in China were shut down following the incident.

[@r.pizzamonkey7379]

Okay I know we just kinda moved past this, but seriously? The log data from the ride computer is stored in volatile memory on the same circuit as the regular control computer? That is some serious incompetence there, like violating common sense incompetence.

[@otterdog102]

The brakes being worn down/broken is exactly why, when I was ride op, one of our tests was to test the E-Stop. Did it work properly? It it didn't, you don't open the ride. Simple as that.

[@SHADOWPAW13]

I hadn't heard of this. terrifying!

Cutting corners is sometimes ok, but NEVER when it involves human lives. When they can be endangered no cutting of any corner is ok.

[@blockstacker5614]

would it be possible to incorporate a mechanism similar to a bicycle coaster brake into some or all train wheels of a train in order to make sure braking is applied any time the train rolls backwards?

[@TimothyChapman]

It's a huge failure on the park's part to assume that this critical repair had been done, and a huge failure on the contractor's part to not do the work. Both should not only pay to repair that ride, but also reimburse the medical bills of everyone who was injured in the accident. Also, I don't think I'd have that much sympathy if the park went out of business because of this.

[@Ssilfyeet]

😢

[@EnzoDiscoveryMoonLight23]

why haven’t companies added some kind of last resort stop where a impact wall (kinda like a crumple zone on a car) between the launch and the station, like something that’s light enough for the staff to set it up within seconds but heavy enough to stop a train at full speed

[@CoasterCollege]

That's not really practical for something that should always be prevented with existing systems.

[@EnzoDiscoveryMoonLight23]

but every year something really bad happens anyways, whether the prevention breaks or staff dont know what theyre doing...@@CoasterCollege

[@jenn82armstrong]

I would be suing the theme park.

[@andreworders7305]

I feel like maybe roller coasters should need inspections every so many years like elevators

[@CoasterCollege]

They do, in most countries including China its yearly. The inspections in this case were not prepared to identify the risks of the ride.

[@philippal8666]

There’s a lot of worry about ‘made in/based in China’. This has substance, there are areas of China where companies produce products of very poor quality. But that doesn’t mean China = secret, poor quality and don’t care. Excellent workmanship is expected by the public in many areas.

[@CoasterCollege]

Agree completely, I have a video series on Chinese ride companies. Some are great and becoming models for the world, others should be avoided at all costs.

[@awestvirginian5858]

The reason it happened was because it was made in China. In all seriousness, the amount of lack of maintenance, ignorance from the top, and cookie cutter refurbishment practices was bound for a disaster at some point. This should be unacceptable in the amusement industry, and stuff like this should be prevented no matter what. Great video Coaster College.

A ride that you experienced the best and joyous Moments and may never get that same feeling again. Tears on the tracks! 💔💔🎢. It’s how I felt when my beloved Colossus was closed but thankfully it didn’t suffer the same fate as its other wooden and steel counterparts. Instead it was refurbished and made over into the badass beast hybrid it is today. ❤️🎢
