This one looks safer than the shuttle, it is lacking the things which proved fatal...

LOX/Kerosene is much safer than LOX/H2...NASA used it on the Saturn V, which worked reliably if you recall that far back.

A suborbital re-entry is pretty low-energy compared to an orbital re-entry...super-high tech heat shields are not required.

For a civilian application, I would prefer solid fuel like Spaceship one..it actually used a solid hybrid, with a liquid oxidizer to provide throttling and restart (?) capability.
