Narrative:

There was a drone flying over parked aircraft at myf airport. East of and directly over the FBO building. We witnessed 2 flights of the drone as we were securing our aircraft after completing our flight. The drone was reported to the police during its first flight; and then again when it came back during its second flight. Unknown if they located anyone connected to it.drone appeared to be about 150 feet above the ground at its highest; there was no NOTAM regarding drone flight occurring at the airport. The drone made multiple passes in an east to west and back during its flights over parked aircraft. I was able to hear the motors of the drone during both of its flight. The drone flew over parked aircraft for about 5 minutes during each flight; while aircraft were actively landing at the airport and making radio position reports.the drone had red and green lights allowing easy visibility against a black sky to see it turn and track it as it made its multiple passes over parked aircraft and then exited to the south appearing to land at an office building.
