Human Factors
I was training a trainee on Local Control West and East. A PA28 called inbound VFR from the west and given entry instructions of 'enter right traffic for 13R report the reservoir'. When he got closer in; in order to depart 2 IFR aircraft that had been holding for release; he was given instructions to 'change to Runway 13L cleared to land'. Which he repeated back correctly; a minute or two later; he called back and asked for us to repeat instructions. He was again given 13L cleared to land; which he again repeated back correctly. Trainee then continued controlling other aircraft; along with many other instructions and clearances. A Commander; IFR; was cleared for take off 13R. After the Commander was off the end of the runway they called us on frequency and said they had an opposite direction on take off. At which point I looked to departure end of Runway 13R and found the PA28 rolling out having landed on 31L instead of 13L. I then keyed up and informed him he was supposed to land on 13L and that he needed to call the Tower. When he called he was given the brasher statement. Upon listening to tapes; we confirmed that all instructions were given and read back correctly. So the situation was a pilot deviation that I did not catch to stop.
Tower Controller described an opposite direction landing and takeoff event when traffic incorrectly landed on the wrong runway; a clear pilot deviation.
