Sister Bertrille's head piece would have worked fine underwater.
As for the TV show, as I recall, it was 'explained' her abilities were a miracle or gift from God. Note, she had no propulsive system and minimal steering, she was entirely relying on the wind to get where she was going in a timely fashion. I don't recall she had the ability to 'just go for a ride', she invariably wound up somewhere where she was needed by others, so the flight capabilities were used by God to carry out His agenda.

The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.
