    en.wikipedia.org/wiki/Liquid-propellant_rocket

    A liquid rocket engine can be tested prior to use, whereas for a solid rocket motor a rigorous quality management must be applied during manufacturing to ensure high reliability. [2] Liquid systems enable higher specific impulse than solids and hybrid rocket motors and can provide very high tankage efficiency.
