n April 1, 2001, an American EP-3E Aries II reconnaissance plane on an eavesdropping mission collided with a Chinese interceptor jet over the South China Sea, triggering the first international crisis of George W. Bush’s Administration. The Chinese jet crashed, and its pilot was killed, but the pilot of the American aircraft, Navy Lieutenant Shane Osborn, managed to make an emergency landing at a Chinese F-8 fighter base on Hainan Island, fifteen miles from the mainland. Osborn later published a memoir, in which he described the “incessant jackhammer vibration” as the plane fell eight thousand feet in thirty seconds, before he regained control.
The plane carried twenty-four officers and enlisted men and women attached to the Naval Security Group Command, a field component of the National Security Agency. They were repatriated after eleven days; the plane stayed behind. The Pentagon told the press that the crew had followed its protocol, which called for the use of a fire axe, and even hot coffee, to disable the plane’s equipment and software. These included an operating system created and controlled by the N.S.A., and the drivers needed to monitor encrypted Chinese radar, voice, and electronic communications. It was more than two years before the Navy acknowledged that things had not gone so well. “Compromise by the People’s Republic of China of undestroyed classified material . . . is highly probable and cannot be ruled out,” a Navy report issued in September, 2003, said.
The loss was even more devastating than the 2003 report suggested, and its dimensions have still not been fully revealed. Retired Rear Admiral Eric McVadon, who flew patrols off the coast of Russia and served as a defense attaché in Beijing, told me that the radio reports from the aircraft indicated that essential electronic gear had been dealt with. He said that the crew of the EP-3E managed to erase the hard drive—“zeroed it out”—but did not destroy the hardware, which left data retrievable: “No one took a hammer.” Worse, the electronics had recently been upgraded. “Some might think it would not turn out as badly as it did, but I sat in some meetings about the intelligence cost,” McVadon said. “It was grim.”
The Navy’s experts didn’t believe that China was capable of reverse-engineering the plane’s N.S.A.-supplied operating system, estimated at between thirty and fifty million lines of computer code, according to a former senior intelligence official. Mastering it would give China a road map for decrypting the Navy’s classified intelligence and operational data. “If the operating system was controlling what you’d expect on an intelligence aircraft, it would have a bunch of drivers to capture radar and telemetry,” Whitfield Diffie, a pioneer in the field of encryption, said. “The plane was configured for what it wants to snoop, and the Chinese would want to know what we wanted to know about them—what we could intercept and they could not.” And over the next few years the U.S. intelligence community began to “read the tells” that China had access to sensitive traffic.
