Setting aside the glamour of the stunt methodology. The premise seems flawed to me. Zero gravity can only exist in free fall, as soon as the sky diver reaches terminal velocity he or she is exposed to the same gravitational field as the rest of us. In the initial interval from leaving the plane until terminal velocity the gravitational experience will go from weightless to fully "weighted". This ignores any buffeting. Safety aside does not look that great an experimental method - there, I've let my physics background out of the bag.

This is an interesting case. We run into similar questions with chemistry conducted on the ground but in the field, where standard lab emergency equipment is not available (eyewashes, showers, etc.)

If the experiments are being done in the context of standard skydiving procedures, overseen by a professional crew, I believe that it's appropriate to leave the aviation risk assessment to the flight planners. The chemistry was started before they left the plane, so it would be interesting to know if the flight planners reviewed the chemistry involved in the process or simply reviewed the chemicals brought on board against the IATA regulations. I see the authors also grew the crystals in mid-air while the crystals were dropping off a 75 foot roof.

Let me know if you have any questions about this.
