Planes Tripling Speed Of Sound Predicted by Bell at Aero Dinner Speeds more than triple that of sound were predicted here last night by the manufacturer who built America's first supersonic air-craft. Enough was learned from the rocket-powered flying laboratory X-1, according to Lawrence D. Bell, to "open an entirely new frontier of flight" at speeds heretofore unknown. The president of Bell Aircraft Corp. of Buffalo N. Y., told some 700 guests at the Aero Club of Washington's annual dinner in the Hotel Statler that necessary power plants are at hand and "stability and control at really high speeds already have been achieved." Mr. Bell, who was one of the three men to receive the coveted Colliers Trophy from President Truman yesterday for their work in breaking the sonic barrier, discussed the known records of present aircraft while pointing out that "the capabilities of late military models are concealed for reasons of military security." Bell Tells of Work. Addressing the club's celebration of the 45th anniversary of the first flight by the Wright brothers, Mr.Bell told how his company had worked with the National Advisory Committee for Aeronautics and Air Force technicians and pilots to produce and prove the supersonic aircraft. Honor guests also were the co-winners of the Colliers Trophy - John Stack, NACA scientist who helped work out the aerodynamic problems, and Capt. Charles Yeager, USAF, who flew the X-1 at speeds greater than sound at Muroc Test Center in the Southern California desert last fall. Meanwhile, Gen. Hoyt S .Vandenberg, Air Force chief of staff, called the high-speed flights of the X-1 the "greatest achievement in aviation" since the early flights of the Kitty Hawk. Speaking at a Collier's luncheon yesterday at the Wardman Park Hotel, Gen. Vandenberg lauded the three men who achieved the Collier Trophy yesterday from President Truman. Mr. Bell, within security limits, recited a few of the difficulties in building the X-1. There was no known fuel pump, for example, to handle liquid oxygen at minus 360 degrees, nor commercial containers strong enough to hold gases at 4,500 pounds pressure per square inch. Lacked Speed Indicator. There were no known air speed indicators to clock the high velocities expected, although exact knowledge was essential to the safety of test pilots. Nor was an altimeter available to measure the height at which the X-1 was designed to operate. Mr Bell, whose company also built the first jet-propelled aircraft in this country, said the X-1 was designed to take off under its own power, but later it was decided to drop the experimental plane from the belly of a B-29 in the interest of safety and fuel economy. "Perhaps the most significant thing about the X-1," Mr. Bell said,"is the fact that the airplane has been flown many, many times in the subsonic, transonic and supersonic ranges in its original configuration without a single change." The newly established Wright Brothers Memorial Trophy was awarded for the first time last night. The initial recipient was Dr. William Frederick Durand, 89, dean of American aviation engineers, who lives at Stanford University, Calif. Helped Develop Jets. Dr. Durand, who has made numerous contributions to the science of aeronautics since the turn of the century, played an important role in the development of jet propulsion plants in the United States during the last year. The annual Frank G. Brewer Award was made to Philip S. Hopkins of Binghampton, N. Y., for "timely achievement in the field of air youth education." Music was furnished by the Naval Academy Band. Special guests included 55 members of the Early Brids, pioneer aviators, all of whom piloted balloons or airplanes prior to 1916. The old-timers came to Washington from all parts of the country to attend the celebration on the anniversary of the first flight. Other Guests.

C., yesterday on the 45th anniversary of the first flight of a heavier-than-air craft. The planes were part of a formation of 200 which passed over the site of the first flight. -AP Wirephoto. ------- Kentucky Police Chief And Aide Are Held In Street Slaying By the Associated Press EVARTS, Ky., Dec. 18-The Evarts chief of police and his only subordinate were in custody today in connection with last night's killing of the accused slayer of a former chief. The subordinate, Patrolman Louis Beaton, is in the hospital at nearby Kenvir with a bullet wound in the hip. Sheriff James C. Cawood and the State police office at Harlan said no charges had been brought against the pair. Investigation of the incident is continuing. Both the sheriff and State police said Chief Isachar Combs and Beaton admitted the fatal shooting of Bryan Middleton, 48, on the street in front of his restaurant. Middle-ton was under indictment and out on bond on a murder charge in connection with the September 14 slaying of Police Chief E. J. Baum-gardner, 50. Claims Self Defense. State police said Chief Combs de-clared he and Policeman Beaton fired in self defense in the line of duty. Chief Combs said Middleton drew two guns and started firing when the officers approached him with a search warrant. The officer said the warrant was for Middleton's home, but that they went to his restaurant to inform him when the shooting took place. The officers said they were looking for contraband liquor. (Harlan County is legally dry.) Sheriff Cawood said Middleton was shot 10 times. Fifth Police Chief. Chief Combs was hired November 11 to succeed George Sellers, who re-signed after being jailed by a county patrolman on a charge of drunken-ness. Chief Combs is the fifth to serve here in recent months. He came from Jackson in Breathitt County to take the job. Earlier H. T. Collier resigned after telling Mayor Elihu Bailey he "didn't want to get shot in the back." Chief Sellers said before he re-signed that the root of the trouble between the police force and the town was "bootleggers." He said they just about ruled the community. ------- UMT (Continued From First Page.) ------- of the National Guard and Organ-ized Reserve Corps with a common Federal appointment and enlist-ment. 2.
