Retired Navy Cmdr. Guy Snodgrass, a former TOPGUN student and instructor, wrote his book because he knew the excitement surrounding the forthcoming "Top Gun" movie sequel, "Top Gun: Maverick," would captivate audiences. But the book is more about learning from his life of service and the extraordinary training he received in the Navy.
