OMAHA - An American billionaire made sure New York health care workers received thousands of medical masks from China.

Warren Buffett let the city's Mount Sinai Health System borrow two jets to retrieve 130,000 N95 respirator masks from a Chinese hospital.

Organizers needed his smaller planes because the Chinese airport was too small for a cargo plane.

According to a source, a Goldman Sachs executive on the hospital board reached out to Buffett for help.

Because of his assistance, Mount Sinai says eight hospitals were able to nearly double their supply of 995 masks.
