These anomalies are fairly common over Mexico City International. From my sources, pilots flying into MCIA that have anomalies detected by radar are usually questioned and briefed thoroughly. I don't know if this is a government or airline exercise but I know it happens. Pilots that have flown north out of MCIA into the United States have experienced some amazing accounts, especially over the state of Chihuahua into southwest Texas.
