A passenger on Singapore-bound Air Niugini flight spoke of the alleged hijack after arriving back in the country this morning.
Lae-based businessman, Mathew Minape, was one of two passengers who restrained a fellow passenger from opening an emergency exit door after inflating his life jacket while the plane was in flight.
He revealed the events that took place inside the PX 392 International flight.
He said a passenger of Indian and Middle Eastern appearance inflated a life jacket before aiming for the emergency exit door.
Minape has not ruled out the possibility of a plane hijack, but says the fellow passenger was deliberate in his actions, but failed.
PX 392 was bound for Singapore when the incident occurred over Indonesian airspace.
Minape said with the help of another two passengers, they managed to strap the suspect to a seat, until the plane arrived in Singapore.
Motives behind the act carried out by the passenger, are still unknown.
Minape said the passenger later told him that he was transiting from Solomon Islands.
In response to reports of the incident, Air Niugini Management has brushed aside claims of a possible hijacking attempt on PX 392. Air Niugini confirmed that the incident happened after a male adult passenger inflated a lifejacket in the aircraft cabin.
Air Niugini maintains that at no time was the safety of its passengers and crew at risk.
The matter was reported to authorities in Singapore, with PNG authorities also investigating the incident.
