Don't forget that the athletes have to deal with 1.8G pullouts AND there are of course options for Martian and Lunar and other percentages of 1 Earth Gravity
I would like to point out that you can achive a negative-G in parabolic flight. This can occur due to turbulence or some other effect where the acceleration of the aircraft exceeds the 9.8m/s^2.
Basically, what happens is that you get sent upwards toward the ceiling. In fact, a slight negative at the start of a zero gravity parabola lifts people off the floor mats in pleasent way.
Because the vomit comet only has like twenty five seconds in a minute long flight
This is incorrect. Parabolic flight typically involves SEVERAL parabolas. For research, NASA and ZeroG both have done between 40 and 60 parabolas, where each parabola experiences anywhere between 20-35 seconds of zero gravity and about as long in 1.8g for the pull-outs. For tourism or a typical entertainment flight, ZeroG may fly about 15 parabolas.
What people need to realize though is that parabolas can be tuned to not just achieve zero gravity, but also reduced gravity such as that found on Mars and the Moon. These parabolas are shallower and therefore the experience is longer.
The flights are pretty darn safe. I am a flight coach for ZeroG and I can attest that our pilots and flight crew are some of the best. The flight crew are an excellent bunch of cargo aircraft pilots that have undergone extensive training for parabolic flight. Parabolas that can produce zero gravity in the cabin require a skill and talent that is hard to come by. We've got experts, and I'd argue that they are AT LEAST as good as the NASA folks.
As for the aircraft, ZeroG has gone through years of proving to the FAA that they are safe to fly. All aircraft mods have been approved by a Supplemental Type Certificate, and we have been granted permission to fly under Part 121 of FAA regulations. Moreover, NASA has been flying these types of flights with the KC-135, a DC-9, and other aircraft in the past, and have flown without any major incidents.
As for the folks in the back of the aircraft, the flight director, coaches and FAA certified Flight Attendant, we are all experienced parabolic flyers, and typically we also fly with an an astronaut. Personally, I have flown with NASA several times, and I can say that my goal is to be at least as good as the experts currently at Johnson Space Center. Point is, we've all got 'parabola legs' if you will, and I think we do a pretty darn good job taking care of our customers in the tourism, entertainment, and research sectors.
Have any questions...Look me up and email me.
Well, I can't dispute that fact that the chemistry requires the hydrogen to be sourced from the natural gas...but the point cannot be missed that oil is most certainly involved in the production of fertilizer...from the electrical power involved to run the rest of the fertilizer production facility to the trucks powered to deliver it. It is very difficult to escape the use of oil for any mass produced product.
Hi All,
Porous tubes are one way we grow plants in space.

The other way we currently grow them is on a agar like medium, called Phytogel, that looks like jello with some fertilizer in it.

Well, we actually fly between 24k and 34k feet....so it's closer to 5 miles ;)
Well, I suppose that actually depends upon the Fantasy Paraball rankings ;)
Wouldn't this mean that Xenon would be mined at the bottom of lakes, and perhaps the ocean?

Trust me, I've done it ;)
