Copter tragedy: The AW139 has been involved in several prior incidents in Malaysia

PETALING JAYA: One of the helicopter types in the mid-air collision during training at the naval base in Lumut has also been involved in a crash off Pulau Angsa near Kuala Selangor just over a month ago.

There were no casualties from the incident in March, which saw the aircraft having to make an emergency landing in the waters during a rescue exercise.
