What Really Happened on Bullet Coaster October 27th 2023? 

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

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.

Clear and concise, with no theory or 20-minute opinionated ramble. Keep up the good work!

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

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

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.

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.

when I tell you I ran here after seeing this pop up in my subscription box. i've been watching these for a while and your quality is always improving, thanks for making these explanations so clear and tasteful!

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.

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.

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!

I love learning about what went wrong when disasters happen.

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

Absolutely love your channel. You do such extensive research and love the visuals along side them So exhausted with maintenance just ignoring rides breaking down and using such cheap ways to fix it.

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.

Dang something hitting my coaster car while loading/unloading is a new fear unlocked.

Just seeing the accident simulation makes my spine and head hurt 😞

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.

Dammm Im early, love the What Really Happened videos much love, we gotta learn for others mistakes

Wow, this could have easily ended fatal. I'm so glad it didn't... and all because nobody wanted to pay for proper maintenance...

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!

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.

Your graphics are awesome man, effort!!

It's been a long time since I seen another video of yours. Great work. Keep them coming.

As fascinating as I find roller coasters, it's such a shame that these things happen and they are not cared for correctly as they should be But a good and informative video, thanks again!

Absolutely love the non-biased factual nature of these videos and your channel in general. Keep up the good work!

Those animations are just great. I really appreciate the quality work you're doing.

Im surprised there is this much information available about something that happened in China

Another amazing video! Can also now officially say I have a coaster college video that takes place on my birthday which... i truly cannot be 100% happy about considering the circumstances

Great video! Great explanation of everything!

This is a video I was actually wanting to see! I was so curious about what happened but could not wait and see what happened because of halloween and etc.

This was really interesting, thank you for your explanations

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.

Hi Today is my second day working at the coaster safety and i wanna tank you again for your help

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!

I hadn't heard of this. terrifying!

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?

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.

Great video! Quick question, if you havent could you cover The Smiler accident at Alton Towers?

good job again

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

Happy Lunar New Year Everyone And Have A Good Valentine’s Day As Well🩷❤️🐲⛩️🏮

it looks like a super cool ride

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.

Can you do a what really happend on Jetline at Gronalund?

As a 53 year old man, this ENTIRE video play inside my head just before the ride starts - This is why us older riders scream going round! 🤣

And that's my issue with Chinese parks.. I actually wondered if they'd have maintenance issues.

I just hope one day accidents at Kennywood and Idlewild have videos made.

Not so fun fact… this happened on my birthday also the animation is AMAZING!!!!

I never heard about this accident 😮 as somebody else said, it’s a rinse and repeat cycle of cheap fixes and eventual catastrophe. Closing the stable door after the horse has bolted.

😢

Of course this happened in China. Wonder if there's a liveleak video of it.

Transportation maimtemamce contracts specify OEM parts. Why not the Amusement Industry?

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

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

It’s always about saving a dollar.

I would be suing the theme park.

Happy Valley sounds shady as hell

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

Can people, just once, not completely suck -.-

Not enough hot oil applied the wheels of Rangoon.

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.

Nice Upload Schedule Man Its On 12:13

Deleting the data… guilty

Bottom line = Chinese Steel, again.

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.

Money hungry higher ups. They don’t care about putting people’s lives in danger! Just as long as their pockets are fat smh

This park sounds like my middle school... Cutting corners wherever possible, not caring for the students (riders)

Go figure, using shoddy Chinese parts caused a wreck. Honestly, I wouldn't trust any ride at this park; if this one's in such bad shape, they almost certainly all are.

The fnaf movie came out on the same day

This is not Galaxy Spin

This is why I hate roller-coaster

Chinese engineering...

Cutting corners in China.... No way!!

This kind of penny-pinching, corner-cutting is pretty much what I expect from Chinese companies. Sadly, the culture there is effectively "if you're not ripping someone off, you're not making money".

I have to unsubscribe. You’ve started duplicating massive sections within your videos, and it completely ruins their flow.

Ooh. Charged, can you say new organ donars😅

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.

Of course it’s China.

I’ll save you nine minutes and 16 seconds, it was made in China which is why it failed. 😂😂😂😂

I guess even our beloved coasters have a life span too. But it’s hard to watch your favorite coasters being destroyed in front of you. 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. ❤️🎢
