[the long march]

A tragedy of immense significance —— almost ended the Apollo program. A sad loss of life all too young.

[Mr. Jazzy]

Not that I am glad this sad event occurred, but this event caused a COMPLETE overhaul of the vehicle and the “go fever” that infected the program.

Yes, heroes were lost, but more lives were saved because a more critical examination was made and efforts to ensure the survivability of future Astronauts and safety of the landings on the moon.

I seem to remember that the culprit was determined to be a wire bundle on the floor of the module that had been damaged and shorted to the metal floor. Unfortunately the test also required a 100% oxygen environment inside. The escape hatch was secured by a threaded device that took way to long to open.
