Narrative:
Mlt was in an orbit pattern northeast of R5503 at 15000'. Small transport departed I43 VFR and requested IFR direct ape requesting FL280. Small transport was radar idented and issued clearance to climb to 14000' for mlt traffic westbound. Small transport was cleared to FL190 when clear of mlt. Mlt turned unexpectedly eastbound and became traffic again with small transport. A 20 degree turn to the right and an expeditious climb through 16000' was issued to small transport. Mlt was communicating with asd at ffo AFB.

Title: LESS THAN STANDARD SEPARATION OCCURRED BETWEEN AN ACFT CLIMBING TO FL190 AND AN ACFT ORBITTING AT 15000'.
Narrative: MLT WAS IN AN ORBIT PATTERN NE OF R5503 AT 15000'. SMT DEPARTED I43 VFR AND REQUESTED IFR DIRECT APE REQUESTING FL280. SMT WAS RADAR IDENTED AND ISSUED CLRNC TO CLB TO 14000' FOR MLT TFC WBND. SMT WAS CLRED TO FL190 WHEN CLR OF MLT. MLT TURNED UNEXPECTEDLY EBND AND BECAME TFC AGAIN WITH SMT. A 20 DEG TURN TO THE R AND AN EXPEDITIOUS CLB THROUGH 16000' WAS ISSUED TO SMT. MLT WAS COMMUNICATING WITH ASD AT FFO AFB.
