Edgartown case closed EDGARTOWN, Mass. (UPI) — A fourth investigation into the death of Mary Jo Kopechne lasted only three hours and 15 minutes. It added nothing to the public knowledge of what happened on Chappaquiddick Island the night of July 18, 1969, but did open the way for the release of the secret inquest into Miss Kopechne's death. The Dukes County Grand Jury questioned four persons peripherally connected with the Kopechine case Tuesday, then announced it had no action to take. District Attorney Edmund Dinis said this meant the case was closed and he would notify the Superior Court clerk there was no proposed prosecution. This would allow release of the impounded inquest transcript under state Supreme Court rules. It should be made public in a few days. Miss Kopechne, 28, drowned in Sen. Edward M. Kennedy's car. Twenty grand jurors sat two hours and 15 minutes Monday and one hour Tuesday, at standard pay of $14 per day, to question the four persons. Was it, in effect, a token investigation? The special session was requested March 17 by the Jury foreman, and Dinis on March 24 concurred in the request. Shortly before 11 a.m. Tuesday, the foreman, Leslie H. Leland, reported to the judge: "The grand jury has no present indictments." It was reported the grand jury had asked for the locked up manuscript and the judge's report of the secret inquest here in January-764 pages covering four days of testimony by 27 prime witnesses—and had denied it. Apr. 8 KANSAN 3 1970 Moonshot in doubt- (Continued from page 1) vinced Apollo 13 commander James A. Lovell is immune to German measles. But they were so unsure about command module pilot—Thomas K. Mattingly and lunar module pilot Fred W. Haise that chief astronaut physician Dr. Charles A. Berry ordered new blood samples of these two taken Tuesday night and rushed to the Manned Spacecraft Center Biomedical Laboratory in Houston, A discrepancy in results of blood samples taken earlier of Mattingly and Haise left project officials concerned not only about the health of the astronauts, but also about the validity of the tests upon which they hoped to base a decision whether to launch Saturday or postpone the mission until May 9. Berry learned Monday the prime Apollo 13 crewmen had been exposed to German measles through working closely with backup astronaut Charles Duke, who came down with the disease last weekend. Berry said if Lovell, Mattingly and Haise "have no antibodies to this virus at the present time, the odds are very high that they would get it." If any of the astronauts show definite signs of contracting the measles, the Saturday takeoff on the 10-day mission would almost certainly be postponed until May 9, the next date on which the sun will be in position to provide proper lighting for the tricky touchdown on the moon. Although their medical status was in doubt, the astronauts held to their pre-flight training schedule. They went through a final rehearsal of the moon landing with mission controllers monitoring them Tuesday, and today planned to practice docking the two spacecraft in lunar orbit and key phases of the moonwalks of Lovell and Haise. A day-by-day list of highlights from the flight plan of Apollo 13, America's third lunar landing, set for launch April 11 at 2:13 p.m. EST with astronauts James A. Lovell, Thomas K. Mattingly and Fred W. Haise: Saturday, April 11—Launch, television from earth orbit, blast out toward the moon. Sunday, April 12-Course correction opportunity, television, mandatory course change to take dead aim on the moon. Monday, April 13—Course correction opportunity. Tuesday, April 14-Television, final outward-bound course adjustment chance, blast into lunar orbit. Wednesday, April 15—Television of landing site from altitude of nine miles, Lovell and Haise make moon landing at 9:55 p.m. Thursday, April 16- Two televised moonwalks by Lovell and Haise to gather rocks; Mattingly conducts scientific experiments in lunar orbit. Friday, April 17—Blast off from lunar surface, television, jettison empty landing craft and crash it into moon. Saturday, April 18—Start back toward earth, two television shows. Sunday, April 19—First home- ward-bound chance to adjust course. Monday, April 20—Course correction opportunity, final telecast. Tuesday, April 21—Last chance to correct aim, splashdown.

Air traffic controllers 'sick,' claims Iowa psychiatrist WASHINGTON (UPI) — Dr. Wayne Sands, a psychiatrist from Des Moines, Iowa, told a federal court Tuesday that about half the nation's air controllers should be in bed because they are too sick or tired to work. Sands also said that 50 to 60 per cent of the controllers need psychiatric care and that an abnormally high number suffer from ulcers, high blood pressure and diabetes. Air controlling involves more stress than any profession he has encountered, Sands said. Sands was the key witness for the Professional Air Traffic Controllers Organization (PATCO) at a hearing on a government motion to cite PATCO for contempt of court. This motion was based on the "sick-out" of controllers that has cut air traffic in half and caused delays at some major airports. The government contends PATCO has violated a temporary restraining order against encouraging or conducting an illegal strike. The "sick-out" was in its 14th day Tuesday and the Federal Aviation Administration said the situation was about the same as Monday when 79 per cent of the controllers reported for work. F. Lee Bailey, the criminal lawyer who is PATCO's executive director, asked how many men would be absent if every controller who was too sick or fatigued to work staved in bed. "Oh, I'd say about half," Sands testified. Luncheon Buffet $1.45 Mon. — Fri. 11:30 a.m. — 2 p.m. Complete Banquet & Meeting Room Facilities Holiday Inn Photo by Ron Bishop Result...
