The problem of turbulence was highlighted in December, when a total of 41 people on two separate flights affected by turbulence in the United States were injured or received medical treatment over two consecutive days.

According to a 2021 report from the U.S. National Transportation Safety Board, turbulence accounted for 37.6% of all accidents on the largest commercial airlines between 2009 and 2018. The Federal Aviation Administration, another agency of the US government, said after the December incidents that there were 146 serious accidents. Turbulence injuries from 2009 to 2021.

Boeing expressed its condolences to the family of the deceased and said it was in contact with Singapore Airlines “and was ready to support them.” The wide-body Boeing 777 is a workhorse of the aviation industry, used primarily for long-haul flights by airlines around the world. The 777-300ER variant of the twin-engine, twin-aisle aircraft is larger and can carry more passengers than previous models.

Singapore Airlines, the city-state’s flag carrier, operates 22 of these aircraft as part of its fleet of more than 140 aircraft. The airline’s parent company is majority owned by Singapore government investment conglomerate Temasek and also operates budget airline Scoot.
