Secret NOFORN
Chapter 5

The loss of yet another U-2 and its pilot made Nationalist Chinese officials reluctant to resume overflights of the mainland. They insisted that their U-2 pilots be given permission to turn on the System-XIII false-angle device during the entire time they were over hostile territory, not just after they had been alerted by the System-XII radar-detection device. The Defense Department acceded to these demands in order to keep the TACKLE flights going. In addition, the Project TACKLE U-2s began receiving even more advanced ECM equipment. $ ^{60} $ Not linked to a story yet.
