It's a miracle nobody died in flight during the program. Exploding oxygen tank, rockets shaking themselves to pieces during launch, getting hit by lightning on top of a flying skyscraper full of kerosene and liquid oxygen....
Starting from the first test pilots, a lot of people died for us to get to the point to launch that flight. So while no one died on the flight, lots of people died just getting us there. If I recall, in The Right Stuff, it's mentioned that those early test pilots had something like a 25% mortality rate.
Gus Grissom, Ed White, and Roger Chaffee died on the Apollo program. I feel it's not polite to ignore that fact even if you add an 'in flight' qualifier.
