Seeing that this woman that propelled herself into the air was 64 there is an excellent possibility that she was not wearing conventional flameproof underwear but a special incontinence undergarment. If this is true there would be a decrease in hot gas flow so as to render the system into an under powered mode. If in fact she did propel herself to the stated altitude then she must have used thrust augmentation such as water injection or reheat. I strongly suggest the Mr. Jackson look into this matter and see if he can modify the design so that the system can in effect generate greater thrust. By doing so, it would remove the weight limit of the pilot and at the same time reduce the intake of the basic fuel. He should also try to solve the problem on non-stoichiometric combustion, which would reduce the amount of unburned methane into the atmosphere.
One other problem to work on is reducing the odor of the propellant just prior to ignition.
