"When, not ‘if.’ Each shot is backed up by one an hour later. If neither one gets through, we have shots farther back which can be diverted—for example easy to shift targets among Delaware-Bay-Chesapeake-Bay group. Same for Great Lakes group. But Dallas has its own string of backups and a long one—we expect it to be heavily defended. Backups run about six hours, as long as we can see North America—and last backups can be placed anywhere on continent. . . since farther out a load is when we divert it, farther we can shift it."
