Sen. Harry F. Byrd., (Ind-Va.) is going to the South Pole next month to participate in a ceremony marking the 50th anniversary of his famous uncle's historic flight there.

Byrd, 64, recalled that it was his boyhood dream to accompany his uncle, Admiral Richard E. Byrd, on his fight half a century ago, but his uncle thought it was too dangerous for a teen-ager.

"He took the position that it was risky and that one Byrd was enough," the senior senator was quoted as saying yesterday in his newspaper, the Winchester (Va.) Star.

The original expedition was arduous. Admiral Byrd and his party prepared a year for it and then had to winter nearby before flying over the pole on Nov. 29, 1919. The admiral was the first person to fly over the North Pole and the first to fly over both poles.

This year's trip is sponsored by the National Science Foundation. The party will include Lawrence M. Gould, 83, who was the admiral's second-in-command. Also scheduled to make the trip, which will leave from Christchurch, New Zealand, on Nov. 25, are Sen. Henry L. Bellmon (R.-Okla.), Rep. John W. Wydler (R-NY), two Navy scientists, three National Science Foundation board members and representatives of the White House and State Department.

"We land right at the pole for a ceremony -- right at the pole," the senator said.
