"F16, IMMEDIATE TURN 180" would have avoided headlines, but no one thought it necessary.
NOT true!
Eight seconds later, the controller stated, "if you don't have that traffic in sight turn left heading 180 immediately."
Initially the Cessna was 300' below the F-16, but apparently continued climbing. The last indication the F-16 pilot had via radio was that the Cessna was 100' below him...
