Today in 1979, a US Vela nuclear-test-monitoring satellite detected the distinctive double-flash signature of a nuclear explosion over the South Atlantic. Although a White House scientific panel later dismissed the possibility, many speculated it was a clandestine Israeli test.

For the 40th anniversary last year, @ForeignPolicy published a special section of eight articles by six experts examining relevant declassified documents and data and explaining "the political and strategic objectives of the key players at the time ...." https://foreignpolicy.com/2019/09/22/blast-from-the-past-vela-satellite-israel-nuclear-double-flash-1979-ptbt-south-atlantic-south-africa/?fbclid=IwAR2dhjcJBzyCINLr8SPPO3-sfMhqXHHPW_n3kLW5SbBLHh603o5o2muvQ1Y">https://foreignpolicy.com/2019/09/2...
