This is a suborbital plane, not a space plane, there is no reentry. If you tried it in that thing you would live about a five seconds.
You've got it. In the Space Shuttle, reentry without a belt under adverse circumstances can be fatal not only to oneself but to others including the pilot.
Are you sure that the return will not be that serious? Think of this with Storms and with some control failures. Think of everyday operation.
Believe me, aircraft designers do this every day with a new aircraft and the pilots have to go through simulations regularly with the worst of scenarios.
They do this in the hope that the they will be able to handle most situations and to AVOID LAWSUITS.
