This transcript is from the tower tapes at Polonia airport near the Indonesian city of Medan, which was the intended destination of the ill-fated Garuda International Airlines Flight 152.
The pilot is identified by his flight number, GIA 152. All other flights in the transcript are from domestic airlines: MNA 241, a landing Merpati flight; and BOU 683, a departing Bouraq flight.
