There is also a risk with Dragon, just estimated to be lower. But both are still space capsules, there is a risk involved with both.

- pfdietz 2y agoThey're safer than the Shuttle was, though. Capsules are designed (I believe) to survive total loss of control on entry, although a purely ballistic entry can have decelerations of up to 15 gees, IIRC.

- pfdietz 2y agoThere's at least one Soviet entry that happened ballistically, IIRC, with no deaths (they had other deaths on entry, but for other reasons like loss of air or tangling of parachute lines.) The peak acceleration on ballistic entry is independent of the ballistic coefficient of the entry vehicle (but is a function of the L/D ratio during lifting entry; even small L/D can greatly reduce the peak acceleration.)
- jjk166 2y agoThis is a semantic failure. There's risk to everything. But there is a qualitative difference between the risk something might malfunction and that something which has already malfunctioned might be dangerous. A house full of fire hazards which is nevertheless not on fire can not be directly compared to a house that is currently on fire.
