I haven't heard much about her trip but I know she went with a group* of nuns and they were very strict. Mostly I've heard that she's 'never going in a plane again.' As far as I can gather from this lady, who is one of the real characters at Zac's, nothing out of the ordinary happened while on the plane but she didn't stop shaking for three weeks.
* I googled the term for a group of nuns. Wikipedia suggested a superfluity, which sounded as though it could be of doubtful origin so I checked a bit more and, according to Oxford dictionaries, this is a fanciful term from the 15th century that probably was never in popular use. They suggest a community of nuns.
