Summary: A United flight in the queue for takeoff was called back to the gate in order to deplane and question a passenger who was quietly reading a book about WWI-era planes.
The passenger was allowed to re-board the plane and continue without incident ... other than, of course, missing his connection, having to rent a car to continue his journey, and miss half-a-day of work in the process. Plus the accompanying loss of dignity for having been publicly singled out as a possible security threat.
