Omar Dhani enrolled in the Air Force Academy in August 1950, and rose through the ranks to become Minister of the Air Force/Air Force Commander in January 1962. His support for Sukarno, and his apparent support for the 30 September Movement in 1965 was his undoing. Shortly after the downfall of President Sukarno, he was arrested and sent to prison by the new government led by Suharto.
In 1995, he was pardoned, released from jail and became one of the main sources for research into the Air Force's role during the coup.
