Orion and Dragon capsules have a pad-abort system.  In the event of a malfunction, the crew capsule will jettison fast enough to escape any explosions.<p>The acceleration will probably knock out the astronauts and cause internal bleeding, but that&#x27;s still better than immolation.<p>Failed re-entry is still going to be fatal, but the Dragon can theoretically recover from a failed parachute with its Draco engines.
