The airplane was operated as a Title 14 Code of Federal Regulations Part 121 flight from Singapore Changi Airport (SIN) to San Francisco International Airport (SFO), San Francisco, California.

According to the flight crew, after just reached a cruise altitude of FL310 when they heard a pop and felt the aircraft shutter, followed by a No. 1 engine fire warning indication.
