What did the declassified documents reveal?

A memorandum on aerial reconnaissance over Communist China, political factors, dated March fourteenth, nineteen sixty‑nine, prepared for the National Security Council’s 303 Committee, is notable for its candid assessment of how resumed overflights might be perceived by Beijing and the potential diplomatic consequences.

AERIAL RECONNAISSANCE OVER COMMUNIST CHINA— POLITICAL FACTORS. 1. Except for satellites, no overhead reconnaissance has been conducted over mainland China since March twenty‑seventh, nineteen sixty‑eight. The stand‑down was ordered at the instance of Secretary Rusk in part because the level of drone reconnaissance over South China in the preceding months, when combined with the frequency of inadvertent overflights of the Chinese border with North Vietnam by U.S. military aircraft conducting bombing raids on North Vietnamese targets, may have given the Chinese reason to believe that the United States was being deliberately provocative.

This signal would reach Peking at a time when there are signs of serious disagreement in the Chinese leadership over how to deal with the United States and would tend to strengthen the hand of those advocating a hard line towards us. 3. The intensity of Peking’s reaction against resumed U.S. overflights would increase considerably if any of the aircraft involved were shot down over mainland China. As has been the case in the past, we can expect the Chinese to put on display wreckage of downed aircraft as tangible evidence of U.S. provocations and hostility. 4. The net result would likely be to extend the period in which the Chinese stance toward the United States will be essentially one of enmity. A curtailment in U.S. hopes of dealing with the Chinese Communists on anything approaching a…
