The pair died when their single-engine AS 202 Bravo plane crashed Saturday during the Bandung Air Show.
"It crashed a few minutes [after takeoff] while the plane was roaring past the crowd of the Bandung Air Show. Both pilots have been confirmed dead at the scene," said Col. Umar Sugeng, commander of the Husein Sastranegara Air Base.
The propeller-driven AS 202 Bravo, which was built as a training aircraft, crashed into an unoccupied building on the base used by the Air Force Officers' Wives Association.
The Jakarta Post said the air show continued, although the remainder of the aerobatics demonstration was canceled.
