The confusion about whether the plane was doing a medevac or a medical supply flight seems to result from the Covid-19 supply flight the day before using the same aircraft.
Captain Don Mendoza, deputy director-general of the Civil Aviation Authority of the Philippines, did confirm that the plane was being used to ferry medical supplies and protective gear to health workers outside Manila trying to slow the spread of the virus.“It was in Iloilo (province) yesterday (March 28). It ferried medical supplies, then went back to Manila safely,” he said.
