MCIA: UFO Witnessed by Airport Workers
"According to observations made by Alfonso Salazar, [the sighting] involved 30 spherical objects that remained visible for 3 hours around 10:45 in the morning.
"A larger object stood out among them, which appeared to travel in a zig-zag motion at considerable speed.
The eyewitnesses include some 35 painters who were working at the Aeromar hangar."
