My father was the launch conductor for Gemini 6 and 7. He went on to be the test manager for the lunar module on Apollo 11 and Apollo 13. So, here’s his summary of the Space X abort- escape test... Great test to prove that the crew capsule can escape and land successfully if All engines shut down in flight. However, since the beginning of the Space Program (Mercury, Gemini, Apollo, Apollo/ Soyez, Shuttle) there has never been one incident when all engines just shut down in flight. Even if this was the scenario (for the first time) the test should have reflected a more worst case scenario. Yet, instead, Space X had the capsule jettison away several seconds ahead of a timed shutdown. This artificially gave the crew capsule a thousand plus yards of “head start” with an advanced velocity before the vehicle actually self destructed from aerodynamic forces. A true worst case ( but realistic scenario) would have been to activate the same abort-escape procedure not until the vehicle began to break apart ( therefore, rapidly burning “exploding” ).. So, in conclusion... A great test under simulated conditions that probably would not reflect a realistic situation. Let’s hope we never have to find out if the abort system works under more stressful conditions!
