Princess Vibavadi was killed by the communist insurgent whilst helping the Border Patrol Police in Wiang Sa District, Surat Thani.

After completing her secondary education, she worked as a secretary for her father, who at the time was one of the most respected poets of the Rattanakosin era and wrote under the pseudonym No.

She had two daughters: In addition to a full writing career, the princess worked for her third cousin, King Bhumibol Adulyadej and his consort, Queen Sirikit of Thailand.

On the morning of 16 February 1977, she set off on what should have been a routine visit to villages and to boost the morale of troops at Wiang Sa District, Surat Thani.

While flying to her destination in an army helicopter, she heard a radio message saying two Border Patrol Policemen had been wounded by a landmine.

As they flew at low altitude over Ban Nua Khlong, the helicopter was attacked from the ground by communist insurgents.
