Singapore's only online vigilante, SMRT Ltd (Feedback), has posted a tribute to one of the passengers on board the missing AirAsia QZ8501 flight.

They revealed that one of the Indonesian passengers used to be an ex-administrator of the Facebook page in its early days.

Without exposing the former admin's exact identity, they only revealed that he was known simply as Admin 3 and also the "psychiatrist".

So far, news of the missing aircraft has been unsettling for Singapore, as it was revealed that the Singaporean onboard the missing flight is a two-year-old girl who was travelling with her father, a British national.

The other Singapore connection is a 17-year-old former student of Anglo-Chinese School (Independent), who was reportedly travelling with his family on board the AirAsia Indonesia plane that vanished on its way to Singapore from Surabaya, Indonesia, on Sunday

The student, named Nico Giovanni, is said to be a local scholarship holder who is currently a first-year junior college student.

The flight was carrying 155 passengers made up of 138 adults, 16 children and one infant, and seven crew members. It lost contact with air traffic control at about 7.24am Singapore time on Sunday.
