I have a hard time figuring out how someone who is known to be truly claustrophobic and/or someone who has a true phobia about heights gets on a Skyliner cabin in the first place. Those people don't want to ride. There have been months of concern shared here from people who suspect the Skyliner will supplant bus transit from the Skyliner resorts to EPCOT and DHS, just as monorails do for the MK resorts. These are people who want a bus and are concerned they won't have that option.
I also don't see the population of people who are truly phobic about these vehicles lining up to jump on because, hey, I'll just push a button and come down by cherry picker or helicopter basket if things so south!! People with self-preservation instincts are not going to want to get off that way, phobia or not. (Then again, maybe there are lots and lots of people out there who are terrified of gondolas but who would love to take a spin in a cherry picker or a helicopter basket? Does anyone have a Venn diagram?)
** Sidebar on the person who was evacuated: All we know about this is from a third-hand account that said "Shortly after the Skyliner stopped due to the incident at the station, a guest or someone else onboard with them in one of the vehicles called 911. The guest was patched through to Reedy Creek as they were claustrophobic, hyperventilating, and had a history of seizures in the past." Was the person known to have claustrophobia? Did the guest called 911? We don't know...so we probably should ease up on the idea that this guest jumped on the ride knowing he/she had claustrophobia and then called 911 when medical symptoms developed.
