The Photo shows how NASA management and regs made Scaled Composites aircraft fly, not how they were designed to fly...

Note that the availability of spacesuits has not saved 14 astronauts on Challenger+Columbus.

Private "space think" is that a risk is a risk and God help you, but if they save on the space suit and the airpak and the climate conditioning, and the bathroom for in case one needs to "go" while under 6g, then 60% to 80% of the mission mass can be saved.

To echo a recent theme, Space travel is dangerous and unpleasant. Let's applaud the astronauts, but not waste money on luxuries, like a self-contained air-pak. If the craft dies, you die, regardless of whether you have your own air tank - refer to that poignant snap of the astronaut helmet that used to be on someone's shoulders!
