What is the fine-grained topic of the following text: I tore through this while on vacation (and, coincidentally enough, flying with a connection in & out of Newark International - got to the part about the first crash just as my flight was prepping for takeoff, which was *fun* in a tempting-fate sort of way), and was just glued to it through to the end. Only return the topic.
Reading a book about plane crashes while traveling by plane.
