After a one-two, Sunday-Monday punch of a "60 Minutes" segment and a Time magazine cover dedicated to the book, Mary Schiavo's Flying Blind, Flying Safe was dropped into bookstores last Tuesday. Last summer Avon paid a million-dollar advance to Schiavo, the Department of Transportation inspector general who resigned in protest after the ValuJet disaster and whose proposal detailing problems in the airline industry was hotly pursued by publishers (Book News, July 29, 1996). The manuscript arrived early this year, with media arrangements demanding that the book be kept under wraps finalized six weeks ago. But will people want to read more than the extensive excerpt that appeared in Time? PW will be tracking the book, which has a 140,000-copy first printing, to see if it lands on any bestseller lists.
