  "account": "The April 6 White House briefing documents the rescue of the downed F-15E weapons systems officer in Iran. The official transcript also describes watching his suspected position with a camera from 40 miles away. That distance concerns the camera, not an established heartbeat-detection range. On April 7, the New York Post reported that two anonymous sources attributed the officer's location to a CIA tool called Ghost Murmur. They described quantum magnetic sensing combined with AI that separates a heartbeat signal from background noise, and attributed its development to Lockheed Martin's Skunk Works. Lockheed Martin declined to comment. In an April 8 telephone interview with the Post, President Trump called the tool important to the rescue, but supplied no technical explanation. The Post and Scientific American separately interviewed physicists who questioned the described capability. The official briefing does not name Ghost Murmur or establish an AI contribution. No public measurements or inspectable technical account establish that the claimed system located the officer.",

On April 7, the New York Post reported that two anonymous sources attributed the officer's location to a CIA tool called Ghost Murmur. They described quantum magnetic sensing combined with AI that separates a heartbeat signal from background noise, and attributed its development to Lockheed Martin's Skunk Works. Lockheed Martin declined to comment. In an April 8 telephone interview with the Post, President Trump called the tool important to the rescue, but supplied no technical explanation. The Post and Scientific American separately interviewed physicists who questioned the described capability. The official briefing does not name Ghost Murmur or establish an AI contribution. No public measurements or inspectable technical account establish that the claimed system located the officer."

The official transcript also describes watching his suspected position with a camera from 40 miles away. That distance concerns the camera, not an established heartbeat-detection range. On April 7, the New York Post reported that two anonymous sources attributed the officer's location to a CIA tool called Ghost Murmur. They described quantum magnetic sensing combined with AI that separates a heartbeat signal from background noise, and attributed its development to Lockheed Martin's Skunk Works. Lockheed Martin declined to comment. In an April 8 telephone interview with the Post, President Trump called the tool important to the rescue, but supplied no technical explanation. The Post and Scientific American separately interviewed physicists who questioned the described capability. The official briefing does not name Ghost Murmur or establish an AI contribution. No public measurements or inspectable technical account establish that the claimed system located the officer.",
