I have to think the imagineers are going to be right on this one. Imagineers run simulators on size of boats and tracks to make sure everything fits together.
I don't work for Disney but find this a particularly insulting insinuation. I am sure Disney hires "real" engineers - not just artists and dreamers. (I am an engineer by the way, but not the same kind as these folks.)
It admittedly was a pretty bad mess-up on the design that they didn't know the Yeti would damage itself due to it's size. I have spoken with actual imagineers on this.
What I was told is that they have a fix developed (for years now) but the ride would need to be shut down for about six weeks, and management doesn't want to do that in a park with a shortage of rides. In addition, 99.999% of a riders never even notice that anything is "wrong" with the attraction, so there isn't a huge motivation to fix the problem.
Exactly right - One thing people seem to want to give no credit to here - most "engineering" in your everyday life involves building things that are mass produced - cars, computers, table saws - and the manufacturers have spent years putting it together to the point that it is seeing the market. A Disney ride is a one-of-a-kind operation, that they have to test "in place". Sure, some of the animatronics are tested in the shop, but really until every piece is in place
Another thing I will defend on Imagineering with being late on things - I don't know how it works at Disney, but where I work, we are often given project deadlines not based on how long it will actually take to do it, but based on a management decision that it WILL be done by this point. Then we are not given the support or manpower to achieve that artificially created target. This well could happen at Disney. (Imagineer: "It will take us 18 months." Manager: "OK, but you have to have it done in 14 months so it is open for the summer season." Imagineer: "Well, that will cost more." Manager: "No it won't. Just do it.")
The same thing might have happened at Rivers of Light - "Oh we can open on Earth Day! Let's open on Earth Day!" "Ummm...we aren't going to be ready." "Yes you will!"
