Browsing the New York Times online archive, I found this curious item:
“Chile gives snub to Major Castro”
It is dated August 19, 1959 and describes how Raul Castro, commander-in-chief of the Cuban armed forces, landed a plane in Santiago after a conference of foreign ministers had ended, ostensibly to take Cuban Foreign Minister Raul Roa Garcia home.
“After a delay in debarking because no suitable ramp could be found, Major Castro was taken to the customs office like any tourist.
The only leading Chilean greeting Major Castro was Senator Salvador Allende, unsuccessful 1958 Presidential candidate of a coalition of extreme Left-wing parties.
At a news conference tonight Major Castro declared “We confess we made an error” in sending a military aircraft here with soldiers.”
