This is a pretty good list

‘Moon walk’ most requested TV image
LONDON (AP) — The first man on the moon is Britain’s most requested video image, finishing ahead of the assassination of U.S. President John F. Kennedy and the Sept. 11 attacks in a list released Tuesday by Independent Television News.
London-based ITN compiled a list of the footage most requested from its archives of more than 300,000 hours of news and feature material.
Neil Armstrong’s first walk on the lunar surface came in at No. 1, an exhilarating moment in contrast to the many incidents of disaster and death on the list.
No. 2 was the news report of Kennedy’s killing in 1963, and No. 3 was footage from the terrorist attacks of Sept. 11, 2001.
The footage is mainly requested by British media outlets and documentary makers. Peter Fydler, director of marketing at the ITN archive, said the list didn’t necessarily record the 20 most important stories of the period.
“What defines this list is what has happened to have been filmed and it should not be taken as a list of the most important historic moments of the 20th century.
Anyone watching these clips should remember that,” Fydler said.

1. First moonwalk (1969)
