Japan's transport ministry has released the transcript of communication between air traffic control and two aircraft involved in Tuesday's fatal collision on a runway at Tokyo's Haneda Airport. It shows air traffic control did not clear a Japan Coast Guard plane to enter the runway.

A Japan Airlines passenger jet collided with the coast guard plane at around 6 p.m. on Tuesday soon after it touched down. Both were engulfed in fire.

The transcript made public on Wednesday evening shows that at 5:43 p.m., or four minutes before the collision, air traffic control instructed the JAL jet to continue its approach to the runway. Air traffic control also informed the aircraft at the time that there would be a departing plane.

At 5:45 p.m., air traffic control cleared the JAL jet to land on the runway.

Ten seconds later, air traffic control instructed the coast guard plane to proceed to a holding point on a taxiway to the runway. The coast guard plane repeated the instruction.

From this communication up until the collision, air traffic control did not permit the coast guard plane to enter the runway.

However, an explanation provided by the Japan Coast Guard paints a different picture. It says the pilot of the coast guard plane said that he entered the runway after receiving permission to do so.

A team of six inspectors from the Japan Transport Safety Board began its on-site investigation in full swing on Wednesday morning and retrieved the flight and voice recorders of the coast guard plane.

The team will interview people, including the pilots of the JAL and coast guard aircraft, as part of its effort to identify the cause of the collision.

The coast guard plane was carrying six personnel at the time of the collision. The incident left five of them dead and its pilot seriously injured.

The JAL jet was carrying 379 people. Fifteen passengers sought medical treatment.
