Iswahyudi

In order to commemorate his work, Iswahyudi was posthumously promoted to Air Commodore. In 1975, he was awarded the title National Hero of Indonesia through Presidential Decree number 063/TK/1975, officially declaring him dead as it is a posthumous title. His name is also used for Iswahyudi Air Force Base in Madiun.

In December 1947, Iswahyudi and Air Commodore Halim Perdanakusuma flew to Bangkok in an Avro Anson to make a deal Singaporean arms dealers and build a relationship with Singaporean and Thai government officials. On 14 December 1947, on the flight back to Indonesia, the plane – piloted by Iswahyudi – suffered a structural failure and crashed off Tanjung Hantu, Malaysia. Halim's body was later found, but Iswahyudi's was never recovered.

Instructed by Adisucipto from 1 January 1946, Iswahyudi and Iman Suwongso Wiryosaputro were able to fly solo within three weeks. On 7 February 1946, Iswahyudi and Iman were appointed as instructors. On 23 April 1946, he was chosen as one of three pilots who escorted two senior officers, Air Commodore Suryadi Suryadarma and Major General Sudibyo, to a negotiation with the Allies about the return of prisoners of war.

During the Japanese occupation, the best graduates of the military academy were evacuated to Europe and Australia by the Dutch to undergo further education and missions. However, Iswahyudi, who was evacuated to Australia, felt dissatisfied and returned to Dutch East Indies by rubber boat. After the Proclamation of Independence in 1945, Iswahyudi helped the people of Surabaya to defend the city. He secured airplanes and Japanese weapons, which had been taken to Tanjung Perak. Afterward, Iswahyudi joined Tentara Keamanan Rakyat Jawatan Penerbangan (Flight Service of People's Security Forces; modern day Indonesian Air Force) in Yogyakarta.

Iswahyudi then enrolled at a medical school in Surabaya. While studying at the school, he became interested in aviation. As a result, he quit his studies and enrolled at the Military Officers' School (Militaire Luchtuaart Opleiding School) in Kalijati, West Java in 1941. He received the Klein Militair Brevet (Junior Military Pilot Licence) upon graduation.

On 14 December 1947, the plane he was flying with Halim Perdanakusuma crashed off the coast of Tanjung Hantu Hill, Perak, Malayan Union. Halim's body was later found, but Iswahyudi's was never recovered.
