Query: You've got to be kidding!

Purchased this book from author at local air show. Book reads like "The Guide For The Recently Deceased" - haphazardly pieced together and confusing. Book protrays author as single handly noticing and solving the problems with the Challenger Tragedy (I missed the chapters on the Hole in the Ozone and the Kennedy Assination). Sad that the author had to create his own publishing company to get published.
