I disagree about the parabolic flights being tougher than the suborbital ones. Parabolic flights seldom pull more than 1.5-2 Gs and only for a less than a minute. After all, they're being flown in aging commercial airliners that weren't built for this sort of thing. A suborbital flight will typically pull 2-4 Gs for a minute or more during the acceleration phase, then 4+ Gs for 1-2 minutes during the reentry phase. That would put a lot more stain on someone, especially if they have some medical problem. We don't want passengers starting to stroke out on us.

I did like the pilot qualifications portion of the linked article.

Pilots of reusable launch vehicles would need to hold an FAA pilot certificate, meet medical standards and be trained to operate their vehicle so it will not harm the public, with emphasis on responding to abort scenarios, emergency operations and procedures that direct the vehicle away from the public in the event of a problem during flight, he said.

Those requirements seem reasonable, especially the portion about directing the vehicle away from the public in the event of a problem. I use the same guidelines for driving as I do for flying - protect those outside the vehicle before those inside the vehicle, and protect my passengers before myself. In an emergency, if I have any control over the vehicle, I'll do whatever possible to avoid hurting someone else, even if it means sacrificing myself in the process.
