Some authors plan meticulously. Before they even start to write, they have a detailed plot synopsis, character biographies, pages on setting, and a detailed backstory to the main tale... at the least. Others just sit down at their word processor and type whatever comes into their head. This trope is dedicated to them. The trope name comes from the phrase "flying by the seat of your pants", a colloquialism for "deciding a course of action as you go along". Please only add examples where the author admitted to doing this. This is not a page for speculation.
