Portsmouth, June 23.
The rescue of 33*men from the ill-feted American submarine Squalus was "the most efficient piece of engineering that ever happened in the world Harold C. Preble, naval architect and one of those rescued from the disabled undersea craft, told a court of inquiry here yesterday.
He said the skill with which the U.S. Navy's "diving dell" was used to rescue all survivors of the disaster was without parallel in naval or engineering history.
He recommended, however, that the Navy change the design of the main engine induction valve on all American submarines. He said they should be equipped with quick closing inboard engine induction valves equipped with remote control. He said this would make it possible to half the great inrush of water which cost the lives of 26 men aboard thet Squalus.—United Press.
