      Hydraulic control systems were popular to design at that time. Consider
      such systems in cars and airplanes that are still used. Phillips was
      probably introduced to the problem in WWII during researches into workable
      fire control systems. The fire control problem involves the fact that
      not only will the airplane be somewhere else when the bullet gets there but
      the ship is not a stable platform either. This involved resolving inputs
      and calculating outputs. Phillips could have seen this as a way of putting
      together a whole lot of economics problems involved in the national economy.
      If an American had conceived of such an idea, he probably would have used
      synchros (waldoes) in the manner of the fire control system that the U.S.
      would field into the seventies.
      The hydraulic conception has a certain elan lacking in the electrical one
      but the electrical one would have been easier to realize even then.
