Flying feather is a traditional street weapon, which is believed to be originated from Philippine. It is a famous weapon in Tawau, Sabah, shot within short distance and being used with the aim to debilitate the victims. Some may even apply poison at the tip of the weapon. We report two cases of severe chest injuries in resulting from flying feathers. Case 1, a 25-year old man sustained left sided hemothorax with anterior right ventricle injury. He underwent thoracotomy and was discharged well. Case 2, a 40-year old man, presented to emergency department with no signs of life, sustained penetrating injury to the left second intercostal muscle, the pericardium and the anterior wall of the right ventricle adjacent to the interventricular septum. These cases highlight the severity spectrum of cardiac injury resulting from flying feathers.
