Upon leaving the office and move 2 steps toward the edge of the sidewalk into the schoolyard, I started to watch in the sky 2 falling objects, approx. to 30/40 degrees towards the north (having as a reference point runway 09/27 of the International Airport of Tijuana "Abelardo L. Rodriguez (TIJ / MMTJ) and a height not very well defined, but taking as reference the ground had an elevation angle of 60/70 degrees . Objects were fireballs and had a trail of red /orange in color with no change in the tail aproximate size of the tail was 7 or 10 times larger than the object and not leaving a visible trail of smoke. At about 25 seconds of having initiated the sighting objects slowed down, immediately after it was observed that from the right hand object another object appeared being same size and color, almost inmediatedly after that objects changed course and speed, at that time I rushed to the second floor to get a better view because the objects were very near the tree top line and i was gonna loose then, I saw the third object was brighter than the other two, I moved towards one end of the building to get a better view but at that time the objects were in the tree top line and lost them. Besides me, several kids of the school (it is a junior h.s. type school) and a couple of teachers saw them, one said that the third object suddenly disapeared. At first I though it was a couple of meteorites or space junk falling down but when they slowed down and changed course that idea went into the tube, I also thought they were skydivers with flares but later on at night while listening to the news on the radio it was reported that the San Diego Police Dept. or the sheriff office did not knew also what was in the sky at that moment.End of report.
