Narrative:

Small aircraft X was VFR practicing on the ILS for runway 20L. When small aircraft X reported the keeley OM, the aircraft was cleared to land. 1 min and 10 seconds later, small transport Y called ready for departure on runway 2R. I scanned the runway and cleared small transport Y for departure on 2R. The aircraft lost separation. The closest they came in my professional opinion was 1000 ft horizontally and 300-500 vertically. The problem was discovered when small aircraft X pilot said 'jesus christ'! No evasive action was taken by either aircraft. I turned myself in an reported to the FAA. Contributing factors: I was told was not contributing. 2 controllers working on shift. Traffic was heavy enough in the previous 2 hours not even to relieve ourselves. Was on position 2 1/2 hours without break, then went to ground control. Was told previous day that I did not make the permanent supervisors position at luk tower (presently temporary supervisor). That it was given to a younger, and I feel less competent controller. Also that the selection was not fair. I was really hurt. Slight headache. Plus I assumed small transport Y was off 20L, hard to tell at the south end because trees obscure about 35 percent of the runway, especially the south end.

Title: CLOSE PROX BTWN SMA ON FINAL APCH AND SMT ON DEP IN OPPOSITE DIRECTION. OPERROR.

Narrative: SMA X WAS VFR PRACTICING ON THE ILS FOR RWY 20L. WHEN SMA X RPTED THE KEELEY OM, THE ACFT WAS CLRED TO LAND. 1 MIN AND 10 SECONDS LATER, SMT Y CALLED READY FOR DEP ON RWY 2R. I SCANNED THE RWY AND CLRED SMT Y FOR DEP ON 2R. THE ACFT LOST SEPARATION. THE CLOSEST THEY CAME IN MY PROFESSIONAL OPINION WAS 1000 FT HORIZLY AND 300-500 VERTICALLY. THE PROBLEM WAS DISCOVERED WHEN SMA X PLT SAID 'JESUS CHRIST'! NO EVASIVE ACTION WAS TAKEN BY EITHER ACFT. I TURNED MYSELF IN AN RPTED TO THE FAA. CONTRIBUTING FACTORS: I WAS TOLD WAS NOT CONTRIBUTING. 2 CTLRS WORKING ON SHIFT. TFC WAS HVY ENOUGH IN THE PREVIOUS 2 HRS NOT EVEN TO RELIEVE OURSELVES. WAS ON POS 2 1/2 HRS WITHOUT BREAK, THEN WENT TO GND CTL. WAS TOLD PREVIOUS DAY THAT I DID NOT MAKE THE PERMANENT SUPVRS POS AT LUK TWR (PRESENTLY TEMPORARY SUPVR). THAT IT WAS GIVEN TO A YOUNGER, AND I FEEL LESS COMPETENT CTLR. ALSO THAT THE SELECTION WAS NOT FAIR. I WAS REALLY HURT. SLIGHT HEADACHE. PLUS I ASSUMED SMT Y WAS OFF 20L, HARD TO TELL AT THE S END BECAUSE TREES OBSCURE ABOUT 35 PERCENT OF THE RWY, ESPECIALLY THE S END.
