Narrative:

I was working 5 positions combined. Worked over 70 operations that hour. Short staffing. B737 requested to depart runway 06. Runway 33L/right was active wind 330/8. Two (2) aircraft C172's in touch and go pattern runway 33R. I was working (2) aircraft on ground control coordinating a runway 06 departure and working a helicopter through the class C airspace. I cleared B737 for takeoff runway 06, totally forgetting the touch and goes in the pattern. C172 was landing runway 33R, and not realizing it was the wrong aircraft I gave instructions to extend crosswind. I did not move my strips. Aircraft advised me he was landing when I gave him instructions to extend crosswind. Seeing what I had done, I instructed B737 to 'cancel takeoff instructions' (2) twice. B737 aborted his takeoff, after rolling about 1500 ft he advised he was doing about 75 KTS at the time. No one to blame but myself. Working 5 position I was also controller in charge. Unable to get overtime working short staffed and not having the second set of eyes. C172 in pattern was not listening in on frequency. If he was aware what I was doing he could of helped. I screwed up!!! Callback conversation with reporter revealed the following information: reporter expressed concern about the staffing level at their facility, which he claims is not keeping up with the increased traffic.
