It's January 27, 1986, at 6pm in Titusville, Florida, a few miles from NASA's Kennedy Space Center. Al McDonald, the director of Morton Thiokol's space shuttle rocket program, is staying in Titusville at a colleague's house. He's in town for the latest mission of the space shuttle Challenger, which is expected to be the most watched launch in the shuttle program's history, thanks to the presence of Christa McAuliffe, the high school teacher who's about to become the first civilian in space. There's so much anticipation around the launch that MacDonald couldn't find a hotel room. Everything for miles around Cape Canaveral is booked. But McDonnell is not sharing in that excitement. Instead, he's sitting alone at his colleague's kitchen table, holding his head in his hands. He's just received a call from someone at Thiokol's headquarters in Utah earlier urging him to postpone tomorrow's launch. According to the weather forecast, overnight temperatures at Cape Canaveral are expected to plunge below freezing, and that's a big problem. McDonald's company, Thiokol, is responsible for manufacturing the thin rubber O rings that seal the joints on the shuttle's two rocket boosters. And based on their testing, Thiokol engineers have determined that the O rings become unreliable at temperatures below 50 degrees Fahrenheit. If even one set of them were to fail during launch, the entire shuttle could explode. Given this risk, delaying the launch should be an easy call to make. But McDonnell knows it won't be. Thanks to the presence of McAuliffe, this Challenger mission has become a media circus, and it was already postponed once this morning after a series of other technical issues. McDonald knows that NASA is under intense pressure to avoid any further delays and that asking the agency to postpone a second time could jeopardize Thiokol's relationship with their biggest client. So McDonnell is going to need to present NASA with data showing why a postponement is necessary. McDonald picks up the phone and dials Bob Ebling, a senior thiocall engineer back in Utah. Hello, this is Bob Ebling. Hey, Bob, it's Al MacDonald here on the Cape. Hey, Al, how's the beautiful Florida weather? Not so beautiful. They're saying it could be 26 degrees during the launch window tomorrow. That low might as well be launching from Chicago. Well, that's why I called. Sounds like you and the other engineers in Utah are unanimous that under these conditions, tomorrow's launch needs to be canceled. Yeah, that's right. I was already worried sick about it. But below freezing? I'm right there with you. But we need to get the decision makers at Diacol and NASA to agree. All right, what do you need? I need to have your guys estimate how cold O Rings will get inside the boosters if the temperature outside 25 degrees, 30 degrees, 35 degrees, et cetera. And then calculate how the O Rings will perform in each and every scenario. All right, then I need you to come up with a definitive minimum temperature for the O Rings to function properly and ensure a safe launch. Well, I can tell you right now, if it's anything close to those temperatures in the forecast, the O Rings are not going to form a tight seal. Yeah, but we need a firm, specific number we all agree on and we need to stick to it. Okay, I understand. I'll put it together. I appreciate, but it's going to be tough. There's going to be a big conference call between everyone at Thiocall and NASA at 8pm tonight. You've only got about two hours to gather the data. Oh, wow. Okay. Well, we'll do the best we can. Don't waste any time putting together any fancy slides. Just get the numbers squared away. We need to make sure this is an engineering decision, not some management decision. Understood. Al, I'll have those numbers for you as soon as possible. As McDonald hangs up, he's already thinking about the next call he has to make and he's dreading it. He needs to talk to Larry Malloy, the hard headed NASA manager who oversees the rocket booster program. McDonnell has a feeling Malloy will be the most difficult to convince in this upcoming meeting. And he needs to begin easing him into the idea of canceling tomorrow's launch. The lives of seven astronauts could depend on it.
