Rainbow Six - Tom Clancy pages 1-29

As i read the first couple of pages of the book the fact that the book was about action kind of brought me to at least pick up the book. So far I have read that the book is about a counter terroreist group called Rainbow Six. Their mission is to counter terrorism around the world. When i first opened up the pages of the first chapter the i expected a lot of shooting and killing, but when I opened the book. It showed that a couple of men with their famliys were traveling. Nothing big right? Wrong these two men were special agents and they were on a hijacked airplane.
