Associated Press:  “The last of thousands of F-4 Phantom jets that have been a workhorse for the U.S. military over five decades are being put to pasture to serve as ground targets for strikes by newer aircraft, the Associated Press reports. The U.S. Air Force will hold a ‘final flight’ retirement ceremony today [December 21, 2016] at Holloman Air Force Base in New Mexico, where the last F-4s are still flying for the U.S. military. . . . McDonnell Douglas – now part of Boeing Corp. – built more than 5,000 F-4s for the Air Force, Navy and Marine Corps. It first flew in the late 1950s, and production ended in 1985.”
