Events which David has been able to describe, as a journalist, include those at the Vatican in 1978 when two popes were elected in astonishingly quick succession. (See A PAPAL SEA CHANGE page.)
His transatlantic crossing, in the 15-metre ketch Sandefjord, is briefly described on the page titled SANDEFJORD, and this experience enabled him to compile and present radio documentaries on the mid-Atlantic island of St Helena, and on Rio de Janeiro, as well as on the Atlantic crossing itself.
In Israel he twice interviewed the archeologist Yigael Yadin (on his excavations at Masada, and on the oldest phylacteries ever discovered) and the former Israeli President Chaim Hertzog (on the Six Day War of 1967, and on the legendary Blue Box of the Jewish National Fund.)
Among other distinguished persons, he has interviewed Charlton Heston, Henry Cabot Lodge, Joyce Grenfell, the recently reelected Chilean President Sebastián Piñera and the then Israeli Ashkenazi Chief Rabbi Shlomo Goren.
David's radio documentaries and special reports on Israel and neighbouring countries include This Year in Jerusalem, I Will Plant in the Wilderness, Vistas of Peace, Christian Refugees in Lebanon, Sinai Settlers Resettled, and The Monastery of St Catherine as well as over 200 weekly features in his 1980s South African radio series Cameos of the Holy Land.
While on the staff of CBN (the Christian Broadcasting Network) as a news co-presenter and journalist with Middle East Television in Jerusalem, David was the 1987 recipient of the CBN Presidents's Award for Excellence.
In print journalism, he has written for The Star in Johannesburg, the South African Catholic weekly The Southern Cross, the now defunct South African news magazine To the Point, the Diner's Club magazine Signature, the British Catholic weekly The Tablet and Catholic New York. He wrote a monthly column for the Christian (magazine) edition of The Jerusalem Post until that magazine unexpectedly ceased publication in February, 2018. (See page titled A NEW COLUMN.)
