Mexico City — 9 July 2026

Mexican intelligence officials and newly unsealed U.S. court documents have revealed the existence of a covert aviation network used by the Sinaloa Cartel to move high‑ranking operatives across international borders. At the centre of the investigation is Mauro Alberto Núñez Ojeda, known within cartel circles as “El Jando”, a pilot now accused of transporting cartel boss Ismael “El Mayo” Zambada to U.S. territory two years ago under clandestine conditions.

A Hidden Flight Path

According to investigative files reviewed by authorities, Núñez Ojeda allegedly operated a fleet of small aircraft registered under shell companies in Mexico and Central America. These aircraft were routinely flown through remote airstrips in Sonora, Sinaloa, and Baja California, areas long associated with cartel smuggling routes.

U.S. prosecutors say one of these flights — a night‑time transfer in 2024 — delivered Zambada to a covert landing site near the U.S.–Mexico border, where he was quietly taken into federal custody. The operation was never publicly acknowledged at the time, fuelling speculation about a negotiated surrender or intelligence‑sharing arrangement.

Cross‑Border Coordination Under Scrutiny

Mexican officials now confirm that the flight was not authorised by any domestic aviation or security agency, raising questions about how a cartel aircraft crossed into U.S. airspace undetected.

Investigators are examining whether U.S. agencies knowingly allowed the aircraft to enter, or whether cartel operatives exploited gaps in radar coverage and transponder monitoring.

Internal memos from Mexico’s Secretariat of National Defense (SEDENA) describe the incident as a “breach of bilateral aviation protocols”, suggesting that both governments may have withheld information from each other during the transfer.

The U.S. Department of Justice has declined to comment on operational details, citing ongoing proceedings.

Corruption and Aviation Infrastructure Infiltration

The case has intensified concerns about cartel penetration of Mexico’s aviation sector. Authorities say Núñez Ojeda maintained connections with airport administrators, flight‑log technicians, and private charter companies, enabling him to falsify manifests and bypass inspections.

Investigators have identified:

– Altered maintenance records for aircraft linked to cartel operations.

– Bribed air‑traffic controllers who cleared unscheduled departures.

– Compromised hangars at regional airports used to store cartel aircraft.

A senior Mexican security official described the network as “a parallel aviation system operating inside the legitimate one”, allowing cartel leaders to move with near‑total impunity.

Legal Fallout and International Pressure

Núñez Ojeda is now the subject of a joint Mexico–U.S. criminal investigation. Mexican prosecutors are preparing charges related to organised crime, illicit aviation activity, and aiding a fugitive, while U.S. authorities are pursuing counts tied to drug‑trafficking conspiracy and unlawful entry into U.S. airspace.

Diplomatic sources say the revelation has strained cooperation between the two countries, particularly as Mexico demands clarity on how Zambada’s transfer was handled and why it was concealed

Broader Implications for Cartel Mobility

Security analysts warn that the exposure of this aviation network may only reveal a fraction of the cartel’s airborne capabilities. The Sinaloa Cartel has long relied on aircraft for drug transport, but the use of planes for leadership extraction and covert negotiation represents a significant escalation.

Experts say dismantling such networks will require:

– Overhauls in airport oversight,

– Real‑time cross‑border radar integration,

– And aggressive monitoring of private charter companies vulnerable to cartel infiltration.
