Narrative

ACR #1; AN SF34; HAD TAXIED FOR DEP OFF RWY 17. RWY 35 WAS ACTIVE BUT THE WINDS WERE LIGHT AND ALMOST A DIRECT XWIND. FT SILL ARAC RUNS THE APCH CTL FOR THE LAWTON AREA AND GAVE US TFC ON 2 T38'S ON PAR APCHS TO FT SILL. I CALLED FOR A RELEASE ON ACR #1 AND WAS TOLD TO GIVE HIM A R TURN TO HDG 240 DEGS AND THEY WOULD CALL BACK WITH A RELEASE. A SHORT TIME LATER; THE RADAR CTLR AMENDED THE HEADING TO A L TURN TO 090 DEGS AND WOULD CALL BACK WITH A RELEASE. I TAXIED ACR #1 INTO POS AND HOLD ON RWY 17. AT APPROX XX25; THE RADAR CTLR RELEASED ACR #1 WITH A L TURN TO 090 DEGS. THE RADAR CTLR CALLED BACK A SHORT TIME LATER; REQUESTING THE POS OF ACR #1. THE ACFT WAS MIDFIELD AND AIRBORNE AND THE RADAR CTLR WAS SO ADVISED. WHEN ACR #1 WAS STARTING HIS L TURN; LESS THAN 1/2 MI E OF THE RWY; THE RADAR CTLR ASKED ME TO CHANGE HIS HEADING TO A R TURN TO 240 DEGS. I COMPLIED. AS THE ACR #1 WAS TURNING SW; I OBSERVED A T38 NBOUND; LESS THAN 1 MI TO THE SE OF ACR #1. BOTH ACFT WERE ON IFR FLT PLANS.
