95. An Accidental Incident

Consider this scenario. You're a pilot who has a medical issue that prevents you from being PIC in your own airplane. And as you're waiting for the reinstatement of your medical, you enlist the help of a friend to sit in the right seat, the real PIC, so you can stay proficient even though you can't log it. But what if there's an incident? Who is responsible: you or the buddy in the copilot's seat?
