Narrative:
While making a practice ILS approach in VFR to apa 35R. The apa tower controller cleared me (as safety pilot) to the MM and to follow traffic now on a left crosswind from runway 17L (opp direction traffic in effect). I was about 3 mi out when I observed an aircraft on takeoff roll from 17L. When we arrived at the MM other aircraft passed overhead about 300' above. At no time during the approach did I feel like a collision was imminent, but I was concerned about the other aircraft. I also wondered why the controller did not resolve the situation by turning one of us off. After we pulled off the runway the controller asked us if she had cleared us to the MM and we said yes she had. No other questions were asked, but she indicated that she was not sure if she cleared us to the MM, or to follow the aircraft on crosswind. In general, I think this controller is more than adequate and does a good job.

Title: ACFT X ON PRACTICE APCH TO RWY 35R, ACFT Y TAKING OFF FROM RWY 17L, BOTH DOING WHAT TWR INSTRUCTS, HAVE NMAC.
Narrative: WHILE MAKING A PRACTICE ILS APCH IN VFR TO APA 35R. THE APA TWR CTLR CLRED ME (AS SAFETY PLT) TO THE MM AND TO FOLLOW TFC NOW ON A LEFT XWIND FROM RWY 17L (OPP DIRECTION TFC IN EFFECT). I WAS ABOUT 3 MI OUT WHEN I OBSERVED AN ACFT ON TKOF ROLL FROM 17L. WHEN WE ARRIVED AT THE MM OTHER ACFT PASSED OVERHEAD ABOUT 300' ABOVE. AT NO TIME DURING THE APCH DID I FEEL LIKE A COLLISION WAS IMMINENT, BUT I WAS CONCERNED ABOUT THE OTHER ACFT. I ALSO WONDERED WHY THE CTLR DID NOT RESOLVE THE SITUATION BY TURNING ONE OF US OFF. AFTER WE PULLED OFF THE RWY THE CTLR ASKED US IF SHE HAD CLRED US TO THE MM AND WE SAID YES SHE HAD. NO OTHER QUESTIONS WERE ASKED, BUT SHE INDICATED THAT SHE WAS NOT SURE IF SHE CLRED US TO THE MM, OR TO FOLLOW THE ACFT ON XWIND. IN GENERAL, I THINK THIS CTLR IS MORE THAN ADEQUATE AND DOES A GOOD JOB.
