According to a report by Mexican researcher Alfonso Salazar, Captain Luis Guillermo Cruz, first officer of a Boeing 737-200, registration XA-MAR, reported a tubular unidentified flying object with a metallic appearance directly over Lake Tequesquitengo in the Mexican state of Morelos.
The sighting occurred on September 16, 2006 at 14:00 hrs. during a flight from Huatulco to Mexico City along air corridor L-47. Weather conditions were clear with some clouds.
According to the witness, he was alerted by an intense reflection visible four miles away from the airline, toward the right side of the cabin. At first he thought it could be a glider, but as they approached, he had a clear observation of an unknown object.
He added that the tubular flying object crossed at the same altitude the airliner was flying but in the opposite direction and with a north/south trajectory, remaining a mile and a half distant from the airliner.
The object vanished 4 minutes later.
