No, Wingman is not available on tape at present, and may not even be in print. There was a (Dell?) paperback around a little while ago. I am planning to look into offering some recordings, but not right away. Meanwhile, be ready to record Wingman off the radio when we get around to repeating it. We also plan to upgrade the Chinwag website, so you might know in advance when a book like Wingman is apt to be repeated.
