a loud bang when the collision happened, several seconds later, they noticed that Flight 7703's left wing was on fire. Survivors recalled the pilots screaming "Fire! Fire!" The passengers and crew then evacuated the aircraft, the airport fire brigade was activated and extinguished the flames on the wing, then passengers and crew were transported by bus to the airport's passenger terminal. Batik Air later stated that the survivors would be flown by another aircraft to Makassar. Aircraft Both aircraft were relatively new, built in 2014 according to an NTSC official. The ATR 42–600 was delivered to TransNusa Air Services in September 2014 and the Boeing 737-800 was delivered to Batik Air in November 2014. Investigation Minister of Transportation Ignasius Jonan tasked the National Transportation Safety Committee with investigating the cause of the accident. Jonan later criticised Angkasa Pura for the vacuum of power in Halim Perdanakusuma Airport's management for the preceding two weeks. President Director of TransNusa Air Services Juvenile Jodjana held a press conference and stated that the tow truck crew had followed the established procedure for towing the ATR-42. The aircraft was due to park at an apron in the south portion of the airport. Batik Air's spokesman also stated that Flight 7703's crew had followed procedures and had been cleared for take-off by Air Traffic Control (ATC). Investigators had retrieved both black boxes from both aircraft and would analyse the content in their facility (the black box from the ATR would probably reveal nothing as AC electrical power would not have been available). They questioned the crew of Flight 7703, and would speak to the air traffic controller that was on duty. NTSC would also interview the ground crew on the tow truck, investigate the taxi procedure, as well as the maintenance of both aircraft. After analysing the content of the black box, it was revealed that Batik Air had been cleared for take off, while the TransNusa Air Services' ATR 42 was still on the runway. The pilots were aware that a collision was inevitable, and tried to steer the plane to avoid a more severe collision. The NTSC later would transcript the CVR and FDR from both black boxes. Owing to a large number of air incident cases in Indonesia, NTSC stated that it would take up to five months to solve the cause of the collision.
