I know everyone on here is furious that the Yeti hasn't been working right for years, but it appears that everyone is stuck in the "anger" stage of grief, and has been for far too long.
It's believed that the Yeti is causing undue stress upon the mountain itself - far beyond what the Structural Engineers accounted for, even in their probable 200% design safety factor.
They designed and built a giant moving "lever" (physics term) that's attached to the structural skeleton of a building (that's what the mountain really is). They THOUGHT they had accounted for the loads, stresses and forces when they designed the thing, but it appears now that they failed.
Fixing a problem like this takes a massive amount of research, analysis, investigation and re-design. They could have probably solved the problem a lot faster if they shut the entire ride down for a few months, but then everyone on here (and all the guests) would be screaming that they shut it down. So instead, they get their flashlights and climb in there after hours to look at things, run tests, take samples, etc.
It doesn't help matters any that they put the Yeti in what appears to be an inaccessible spot, or at least one that makes it almost impossible to replace/repair. This goes back to a lack of planning in the beginning.
If everyone wants to be mad at someone, be mad at the people who originally designed the ride. They failed. Joe got his way, and he has a giant monster inside a believable mountain - but function gave way to aesthetics (Architects/Visionaries always win over Engineers) and now we're left with a mess.
Re-engineering something that's already part of a building, and repairing something that's inside a steel cage is a daunting task. They have to analyze this problem from the foundation up to the Yeti, and re-calculate the stresses applied to each and every steel member in the building before they can even begin to propose a solution.
And for all we know, maybe they HAVE proposed a solution, and it's going to cost $25 million and force the ride to close down for 6 months. And maybe, if that's the case, Disney is taking a hit on the broken Yeti while allowing one of very few E-tickets in AKL to stay open.
Nobody knows, but we're quick to yell and point fingers at the people (i.e. CMs and Guest Services) who are quite aware of the problem but who have absolutely NO say or control in what is being done about it. I'm pretty sure the people responsible for the fix are well aware of the situation, and aren't going to risk skipping important steps in order to make some Facebook fans happier for 5 minutes.
Just my two cents.
