Then came the second jump. With a dull thud, heavy boat shoes hit the life raft's floor. They came in fast and threatening. The floor pitched, and Doug Ritter, executive director of Equipped to Survive, tumbled into me as he slid out of the doorway and off to the side to make way for the others. Quickly, our consultant on this project, Steve Callahan, the author of Adrift, the chronicle of his 76 days in a raft crossing the Atlantic, and CW managing editor Elaine Lembo followed, with knees and elbows flying. And then there were four of us under the fabric canopy, sizing up the space and imagining what it would be like if we were really calling this home until rescuers arrived, what boarding might have been like if it were taking place at night and in heaving seas, and, most important, how easy, even in these controlled conditions, it would be for someone to be injured-when jumping or when being jumped upon-and for serious complications to quickly set in. Elaine, in fact, was about to get a too-real taste of trouble as we went through our planned assessment drill.
