The head of the Spanish division of global technology company Siemens and his family were identified as five of the victims who were killed on the ill-fated helicopter that plunged into the Hudson River Thursday, according to law enforcement sources.

Agustin Escobar, president and CEO of Siemens in Spain, his wife and their three children were killed in the fiery crash in which a tourist chopper plunged into the murky waters.

Gut-wrenching photos on New York Helicopter Tours website show the bundled up five family members smiling in front of the Bell 206L-4 LongRanger IV helicopter and strapped inside the aircraft.

Escobar’s spouse was identified as Merce Camprubi Montal, ABC News reported, citing law enforcement sources.

“No matter how hard things got, he always stayed calm and kept it together. He had this way of making things feel OK, even when they weren’t,” Juan Ignacio Diaz, who used to work with Escobar, told The Post Thursday night.

“And he never forgot what mattered most — his family.”

The loved ones just got into the Big Apple from Barcelona earlier in the day, law enforcement sources said.

The identity of the pilot was not known as of Thursday night.

The sightseeing chopper broke apart midair and then plummeted like a rock into the Hudson around 3:15 p.m.

Four victims were pronounced dead at the scene and two more were declared dead at the hospital, officials said.

The cause of the crash was unclear with an investigation underway.

Escobar had 25 years of international experience in which he led businesses across the globe, including the US, South America, Spain and Germany, according to his LinkedIn profile.

He had been CEO of Siemens Spain since late 2022.

When the German-based multinational company announced his new position, his predecessor, Miguel Ángel López, said Escobar’s work has been key to Siemens’ success in the field of mobility and transport.”

He was also the Global CEO of Rail Infrastructure at Siemens Mobility since last October, according to the profile.

His business acumen was only exceeded by the relationships he had with his family and friends, his pal Diaz said.

“He was such a great person — kind, steady, and always there when you needed him,” Diaz said.

“He was a loyal friend, someone you could really count on.”

Diaz, who previously worked at Siemens, also called Escobar “a true family man.”

“He loved his wife and kids so much — they were everything to him,” he said.

“He was a loving, fun, and just really cool dad,” Diaz said. “I’m going to miss him and his family.

“I love you my friend.”
