Examining the Influence of Safety Management in the Personal Spaceflight Industry
Suborbital flights will soon take flight as a viable commercial operation. Operators such as Virgin Galactic, along with their designer Scaled Composites, will be responsible for safety of the flight crew, Spaceflight Participants and indeed the uninvolved public beneath their flight trajectories. …

Assessment of Iso-Ahola’s Theory of Tourism Motivation on Willingness to Fly as a Point-to-Point Suborbital Space Tourist
<p>Suborbital space tourism involves flight in an air vehicle to an altitude exceeding 100 kilometers (62 miles). This altitude is referred to as the Karman Line and the edge of space. Point-to-point space travel is transportation in an air vehicle where the vehicle flies around the earth in space …
