New York Times: “The most alarming theory under consideration by some U.S. officials is that the objects are sent by China or another power in an attempt to learn more about American radar or early warning systems.”
“A senior administration official said one theory — and the person stressed that it is just a theory — is that China or Russia sent the objects to test American intelligence-gathering capabilities. They could be sent to learn both how quickly the United States becomes aware of an intrusion and how quickly the military can respond to such an incursion, the official said.”
Wall Street Journal: “In the wake of the objects shot down Friday and Saturday, U.S. officials have reached out to research agencies to determine whether the high-altitude craft might be related to their work, U.S. officials said. But the U.S. hasn’t ruled out that they might be of foreign origin.”
