Gov. Maura Healey ordered flags in Massachusetts to continue flying at half-staff on Friday in honor of a 24-year-old Air Force member who died on a training mission off the coast of Japan last month.

Jacob “Jake” Galliher was killed Nov. 19 along with six of the seven other airmen aboard the lost CV-22, whose bodies have been recovered as of Dec. 14. The eighth airman is still missing and is presumed dead, the Air Force said.

All flags, including the United States flag, will be lowered from Dec. 15 until sunset on the day of interment on Wednesday, Dec. 20.

Flags were already at half-staff since Dec. 7 in honor of Waltham Police Officer Paul Tracey, who was killed when a car collided into a work site in Waltham that he and National Grid employee Roderick Jackson were working at on Dec. 6.

Galliher was a 2017 graduate of Taconic High School in Pittsfield and “a deeply beloved member of this community,” the city said in its repatriation announcement. Galliher, his wife, Ivy Groshong-Galliher, and their 2-year-old and 2-month-old sons, had lived on a military base in Japan before his death.
