This Air Canada incident involving a celebrity wouldn't have even caught my attention but for a peculiar contradiction. The airline insists that the scheduled flight from Heathrow to Toronto was diverted to St. John's, Newfoundland for a medical emergency. But the linked report implies that the only passenger disembarked was an intoxicated woman who was taken by police, not ambulance, and charged with a number of things, including endangering safety of an aircraft.
Although the Aviation Herald article refers to Ms. Walsh as "the ill passenger" I suspect they have incorrectly inferred that and that in fact Air Canada did divert for a medical emergency and simply have released no information on its nature. This is supported by the fact that Aviation Herald articles normally give no information on the nature of the medical emergency in such diversions and that the police were called 30 minutes after landing. If an airplane needs emergency services, ATC will make the necessary calls to have them meet the plane as soon as they arrive. It looks like the A330-300 diverted for medical reasons, was met by an ambulance for the actual ill passenger and then when Ms. Walsh proved to be unready for their subsequent departure, the crew called police.
The Star article almost makes it look as if Air Canada is trying to cover for her, "No, no, she wasn't sick, she was drunk!" but I'm sure it's just an error in the writing. That just goes to show how easy it is to have the facts:
1. airplane diverted for medical emergency
2. intoxicated person arrested
and just by sewing them together into a paragraph make the article say something else. I'm sure I do it all the time.
A later article in the same newspaper gives Ms. Walsh's side of the story. She apparently offered her first aid skills in relation to the medical emergency and when she was rejected because they wanted an actual doctor, she persisted, and pushed another passenger who told her to shut up. When asked to leave the airplane she complied, but became enraged when she realized that she was being taken into police custody. She cites an alcohol reaction with sleeping pills and a missed dose of other medication as contributing to her overreaction.
