Contrary to the prevailing version, if there was no visibility, it was human, not meteorological, fault. General Dario conspired with the governor and the commander of the Curitiba Air Base to prevent the arrival. The runway was kept dark. The pilot could have landed at Bacacheri Airport, whose commander had not blocked the runway, but for no known reason he did not and proceeded to Porto Alegre. Had they landed in Curitiba, the generals would have been met by Dario - and officers willing to arrest them.
