“In reality, it’s even better than that because McDivitt is actually in the process of undertaking the docking, and the stakes were very high. This was the first time we’d had humans in a spacecraft incapable of getting them home, because they were testing the lunar module and it didn’t have a heatshield. So, if they didn’t make this docking, they couldn’t have come back. It’s an incredibly precious moment, an intense moment, a historic moment.”
