proximity warning system provided additional indications, for example if a plane was heading for a mountain slope or if it was too low for a landing. This was an automatic supplement to more conventional altitude warning systems, already installed on most Pan Am aircraft. In the aftermath of the crash, Pan Am stopped their Hong Kong to Sydney flights via Bali. A monument was erected by the Regent of Badung Regency Wayan Dana and Bali Governor Soekarmen, with the names of 107 victims inscribed on the monument.
