A man and a woman on a pierIn the summer of 1985, an engineer named Roger Boisjoly noticed a flaw in the solid-rocket booster that was used to help launch the space shuttle. The large rubber O-rings that seal the joints between sections of the booster were experiencing erosion—particularly in cold weather when they shrank. When the joints are compromised, the booster can leak super-heated gas from its solid fuel, acting like a cutting torch that can burn through the metal skin of the adjacent external fuel tank and ignite its explosive liquid hydrogen fuel. Foreseeing that the problem would result in catastrophic failure, he sent a warning memo to decision makers at both his company and NASA. That warning and several more that followed were ignored. The morning of January 28, 1986 was crisp and cold. Unwavering, NASA continued with the launch of the space shuttle, Challenger. The first 60 seconds of the launch seemed to go according to plan. A nervous Boisjoly turned to a colleague and said that they had dodged a bullet. Fourteen seconds later, his worst fears were realized. The Challenger exploded taking the lives of seven people. In a similar way, marriages can experience eroding intimacy. These problems can seem small; however, over time, they can cause a marriage to break apart. It’s important to see the warning signs and act on them. Are you and your wife experiencing these four signs of an unhealthy marriage? More
