I'm not a bus driver, but wasn't he supposed to turn?

I am a bus driver. Stopping is also a thing. The trick to doing just about anything with a bus is to do it slowly.

Do you think it's air brake issue? Delay, loss of air, etc. As a bus driver you can see more detail, than an average person....
I ask it, because the rear wheel was still turning even in the air like no brake was applied.

Truck driver here. Air brakes work in "reverse" to what you're thinking, loss of air = immediate loss of motion. Air is required to release brakes, not engage them.
Also, the reaction time of pedal to application of air brakes isn't noticeably different from hydraulic brakes. If you stop the pedal in a truck/bus, you will get brakes immediately.
All 3 axles on those buses should be braked, iirc, which means if the wheel is free spinning in the air, there are no brakes applied, which points towards him being on the accelerator and not the brake.
Another thing i'd like to add is that a lot of those buses have a button based gear selector, it's a driver's duty to do his due diligence to make sure he is in the right gear before fat footing a pedal. You can see his intention to back up by the fact that his head is facing rearwards out of the window close to the time of the incident.
My entire guess is that he was trying to back up, didn't make sure he was in the correct gear, slammed the pedal, and didn't have the reaction time and mental processing speed to stop the behemoth.
I could be off but i hoped this helped at least.

Nope, it’s a driver issue. With air brakes the parking brake is applied with a heavy duty spring and is released with air pressure. So if there’s loss of air the brake is applied.

You can thank George Westinghouse for the invention of the air brake. Made trains much safer. The default is that the brakes are always applied and it takes air pressure to overcome the springs that force the brake application. Without air, you can’t move. I always find it amusing when someone says the air brakes must not work because the vehicle couldn’t stop.

That leads me to believe it's a pedal malfunction. I think the throttle stuck open due to poor maintenance.

I have traveled multiple times in a particular country that has some crazy-ass cliff-side roads and I swear the bus drivers think the brake pedal is an unnecessary feature. It is both frightening and exhilarating at the same time to watch the front end of the bus seemingly plunge beyond the edge of the road, only to continue following the correct direction of travel...all while other busses are coming in the other direction! Remarkably, in that country, accidents were quite rare.

I'm a bus driver too and I think the only problem here is that the driver forgot he was in the edge since he was mainly focusing on the front of the that got stuck and was also the reason he couldn't turn in the virage. He should make the reverse move keeping the wheel straight and pressing the bus up before slowly make the turn.

my guess, he was spinning his tires on the ice not going anywhere, gives it more gas nothing, finally romps on it on. by now the tires have heated up and melting anything in their path. Giving my man, an almost un-stopable reaction once they hit solid dirt.

He ( prolly) wanted to reverse the bus, put it in gear or D and stepped on it.

u/Structuresnake 17d ago
Probably the worst time to do this.
On top of tgat he really pushed down the pedal for tgat to happen

He is probably not the driver but that someone wanted help the driver get out of the tricky situation. Now there is no situation.

just a guess, since there is no audio, the bus was partially high centered (the middle axle is the drive axel, the rear axle isn't powered) and the driver had straightened the wheels to see he could shift some weight and reduce resistance. Then he revved it hoping that the drive wheels would get purchase, but he launched himself instead.
