Istanbul Sabiha Gökçen Airport UAP Incident

The Event

In late January 2025 (reported circa January 28th), Sabiha Gökçen International Airport in Istanbul experienced a significant UAP incident involving multiple flight operations and coordinated military search efforts. Pilots approaching or operating within the airport's airspace reported unidentified objects detected on their radar systems, triggering automated TCAS (Traffic Collision Avoidance System) warnings designed to prevent mid-air collisions.

Immediate Response

Upon receiving the collision avoidance warnings, pilots immediately reported the contacts to air traffic control. Turkish authorities launched a coordinated response involving:

• Airborne search operations by military and civilian aircraft
• Maritime search operations in surrounding waters
• Ground-based search efforts

The response reflected the severity of the initial reports and the potential aviation safety implications of unidentified objects in controlled airspace.

Characteristics

The radar contacts were reported as unidentified objects with no visual confirmation by many witnesses, though some accounts suggest visual sightings as well. The TCAS warnings indicate the objects were tracked at altitudes and positions consistent with actual air traffic, suggesting either a solid physical object or sophisticated radar reflective properties.

Investigation and Theories

Despite extensive searches, authorities found no physical evidence, wreckage, or definitive identification of the objects. In the absence of concrete findings, investigators and aviation experts proposed several explanations:

• Unauthorized drones: Some pilots speculated the objects could be unregistered or smuggled drones operating in restricted airspace
• Atmospheric phenomena: Electronic anomalies or unusual atmospheric conditions were considered
• Radar artifacts: Technical malfunctions or radar reflections from conventional aircraft

However, no conclusive explanation was provided, and the incident remains officially unresolved.

Context

The Istanbul incident occurred amid ongoing UAP activity across Turkey in early 2025, including the more publicized Gaziantep Airport incident (February 2025). Both incidents involved military or civilian aviation authorities and occurred at major Turkish airports, suggesting either a coordinated phenomenon or increased reporting sensitivity.
