Not sure about that but indications are it won't have an escape system like other manned craft.

Space Shuttle didn't have an escape system either; its total death toll was 14.

  > Space Shuttle didn't have an escape system either To be pedantic, the early flights had ejector seats for the pilot and commander, and the post-Challenger orbiters had a 'fire-pole' bail-out system. These systems could only be used in a very limited set of circumstances.

  Absolute numbers don’t really mean much. More than 14 people have died since this test flight on American roads. Shuttle death rate was about 1 in 75, which is insanely high.

    How does that compare with other rocket systems?

      Pretty poorly, Soyuz has 4 fatalities (Soyuz 1, Soyuz 11) during it's over 140 flights, Crew Dragon has none.

        That's a unnormalized metric: shuttle had two failures in 135 flights and generally carried up way more people per flight and also did way more stuff per flight.
      - midasuni 3y ago
        And how many failures in the most recent 100 Soyuz flights? Crew dragon hasn’t had anywhere near enough launches to compare. F9 itself though has and its a great system. Going to be a long time before it’s a trusty as a 737 max though.

    What are the units on 1 in 75? People? Missions? To compare with other launch methods, you'd need to use the same metric. IIRC, Soyuz is actually more deadly, but it's been some time since I've seen the stats. Both Soyuz and the Space Shuttle are by far the most deadly form of transportation.

      Broadly the same - 7 seats a launch, about 2 failures in about 150 launches, or 14 seat failures in 1000 seat launches. The early launches didn’t have 7 people on but it’s not really relevant. Worryingly for the shuttle the second failure was well into its lifespan. 5 failures in 50 launches then no failures for 200 more launches is better than 1 failure every 60 launches despite the second being theoretically better from the numbers.

      You can either use 14/833 crew positions (individuals flew more than once), or 14/355 actual people who ever flew on the shuttle. You could also use 2/135 missions. I suppose an argument could be made for 2/269 as well if you want to count launch and reentry as separate risk events.
