Priscilla is a very disorganised pink ATR42 with two large turbofans. She drives everybody scatty when she arrives at the Terminal without her paperwork!

There is a story in the first book telling how Priscilla manages to fly off without some of her passengers, and how Archie has to find her and get the passengers on their way..... not without some exceptional navigation and flying on Archie's part first, though!
