New York Times bestselling author and Breitbart News Senior Contributor Peter Schweizer details in his new book how the Chinese Communist Party (CCP) is "using our openness and generosity against us" by sending thousands of future military pilots posing as civilians to the United States to learn how to fly.

Schweizer's latest exposé, The Invisible Coup: How American Elites and Foreign Powers Use Immigration as a Weapon, delves into the little-known concern of Chinese pilots being sent to the U.S. for training with "virtually no oversight" before returning and serving in their own country's military.

"The People's Republic of China has a pilot problem," the investigative journalist writes in The Invisible Coup. "Beijing needs five thousand pilot cadets every year to meet the demand for both military and civilian pilots. Because the Chinese military tightly controls the country's airspace, it can domestically produce only about 1,200 pilots a year. So, Beijing quietly erected a system to train three thousand of them a year in the United States."

"Across the US, at least sixteen flight schools, operating out of taxpayer-funded airports, are training Chinese cadets—sometimes without disclosing their foreign military ties," he continues. "They do so by sending future military pilots to the United States posing as civilians to learn how to fly."

This also applies to Chinese helicopter pilots, who receive American training by the thousands after entering the country on student visas with "minimal scrutiny," Schweizer writes.

"How this happened is a testament to Chinese ingenuity in manipulating our immigration system for subversive purposes and using our openness and generosity against us. It is also a tribute to American innocence, or at worst, ignorance."

One of the several flight schools that the Civil Aviation Administration of China (CAAC) sends future military pilots to is Sierra Academy of Aeronautics in Atwater, California — where most of the students are Chinese nationals.

Schweizer argues that this is not by mistake, but rather by design.

Sierra Academy's owner, John Yoon, has several related companies with "extensive Chinese ties," Schweizer reports, adding that Sierra Academy has developed plans to create a cargo facility at California's Castle Airport to fly goods in and out of China — and were "hoping to use EB-5 money from China to do it."
