So you're saying free and 1 non Tier 1 FP?

And add scooters to the mix the evac may be difficult to say the least. The old MK sky liners broke down frequently. But I donít remember any evacuation efforts. Instead we just hung there and waited until it starts again.

Detach lifts (ones where the haul rope keeps moving at about 1000 fpm and the cabins are then accelerated from a slow pace, matched to 1000 fpm, and then clamped onto that already moving cable) are complex pieces of equipment. When you go into the drive stations... you instantly understand about that. It is 'computer city". The lift has to "know" wher each part of the system is at any given time.

When it works ... they are amazing. When something goes wrong...... it often takes a while to find the situation and correct it.

Luckily most faults are minor and after maybe 5 minutes they can restart it all back to normal.

The next class is kind'a more major issues.... but the haul rope in these cases can eventually be run at a very reduced (crawling along) speed until they can offload all the cabins at the normal terminals. Read this also as "reduced ventilation rate".

The class I worry about at WDW is the rarer ones... where they can't run the haul rope. The cabins a re dead in the water until they can evaluate the issues and repair them. This is when they have to call a lift evac. Everyone has to come off that lift by something other than a normal manner.

People neat the terminals at low heights can be gotten off with ladders. After a certain height,..... it is the crane units or using ropes and belaying them down. Over water either they have fancy boat cranes... or it is likely belaying.

One of the biggest issues evac teams face is people not wanting to get out! A lot of time is wasted dealing with psychological issues. Coaxing someone afraid of heights to step out over empty space. It is a real art. Been there, done that, bought the T-shirt multiple times. If it is the belay method... it is WAY worse than it will be with the cranes..... but those will not 'feel good' to many people.

In the snowsports industry what we always feared was the cold. A brutally cold day with high winds and a lift going down... and we were racing time due to hypothermia and frostbite. In Florida in the summer on a 100F day with high humidity, the race they will have will be with heat exhaustion and heat stroke and dehydration. Remember, when the cabins are not moving at 1000 fpm....... no ventilation.

If they don't have a LOT of those evac crane units and the people to RUN those evacs.)....... it is going to take a long time to get everyone off. In the winter a mile long ski lift can take hours to fully evac. Some of what we deal with is different, but with the runs over water...Disney will have its own set of challenges.

I'm sure they are preparing. But history in the snowsports industry says....... it won't be enough to prevent some real problems when it happens.

best,

.............john

The runs over water are minimal. It looks like there will be drivable surface under most of the gondola route for the lifts to easily traverse.

There are also barges for evacs over water.

Given Disney's reputation and record, I suspect their standards for training will be extensive. Another expert already noted that Disney's testing process is significantly longer than he's seen elsewhere with the same type of system.

I don't doubt for a second that whatever scenario we can come up with, Disney has already thought up and planned for.

I think it will be easier to evac than a stopped monorail that can't be towed back.

Blog Mickey has evacuation photos. It looks like Disney will have pretty good access to the gondolas.

Okay. 100% on board with a procedure. Being that I am terrified of heights when I am not completely enclosed, I may never ride that thing due to the fact that I would completely flip out on that cherry picker platform!
