Jaime Roldós Aguilera

Jaime Roldós Aguilera (November 5, 1940 – May 24, 1981) was an Ecuadorian politician who was the 33rd President of Ecuador from August 10, 1979 until his death on May 24, 1981. In his short tenure, he became known for his firm stance on human rights, which led to clashes with other Latin American governments and poor relations with Ronald Reagan's United States administration.

On Sunday 24 May 1981, a plane in which he was travelling crashed, killing all passengers including Roldós and his wife. Controversy surrounds the circumstances of the crash, including the absence of a black box. Multiple investigations were carried out at the time, and in 2015-16, but no definite cause was determined.
