The design is the epitome of simplicity with one minor drawback. The hydrogen peroxide fuel must be of a very high percentage and not the kind you buy in a drug store (Chemist) and as such it is highly unstable. This same concept was used on the Redstone missile to drive the turbopumps that delivered the fuel and oxidizer to the rocket engine. In the convoy used in the deployment of the missile was a truck carrying a barrel of H2O2. It was always at the rear of the convoy. The internal barrel pressure and the liquid temperature were constantly monitored and if it looked like either the pressure or temperature were rising the barrel was kicked off the truck and very shortly thereafter it exploded bleaching everything it contacted. Getting into this aircraft is like strapping yourself to a bomb. The flying manpack used the same principle but it could only carry enough Hydrogen peroxide for a few minutes of flight.
