It's the book where Isaac Vail's annular theory was abandoned and they went with Henry Morris' idea of a vaporous suspension of the flood waters in the thermosphere.
I remember reading that book in the early 70's- and me being a science whiz in school, didn't put 2 and 2 together= all the weight of that suspended water vapor would have crushed all life Earth on just like the thick atmosphere on Venus. That whole book is filled with bloopers.
