[apollo] Classified Apollo 11 anomaly threatened to crash first moon astronauts … How a problem with the Service Module almost killed all the Apollo 11 Astronauts close to home. ‘About 15 minutes before the astronauts splashed into the Pacific Ocean, the CSM fully separated into its two parts. This was necessary because only the command module (which held the crew) had a heat shield. The heat shield protected the astronauts by deflecting and absorbing the scorching energies created by plowing through Earth’s atmosphere at about 25,000 mph — more than a dozen times as fast as a speeding bullet. The service module became useless and posed a collision risk after the two parts separated, so it was supposed to skip off Earth’s atmosphere like a stone thrown across a pond. But it did not.’
