Air India Flight from Delhi to Mumbai Signals Hijack Alert

Air India Flight AI2957 Sparks Security Alert with False Hijack Signal

On January 27, 2025, Air India flight AI2957, en route to Mumbai (BOM), triggered emergency protocols shortly after takeoff from Indira Gandhi International Airport (DEL). The aircraft transmitted a hijack signal at 8:40 PM, raising significant concerns among aviation authorities and leading to an immediate security response.

With 126 passengers on board, the flight operated by an ex-Vistara Airbus A320neo, registered as VT-TQM, quickly became the focus of a large-scale security operation.

Air India Flight Hijack Incident

The transmission of the hijack signal prompted Delhi Air Traffic Control (ATC) to implement comprehensive security measures, alerting multiple agencies, including the Indian Air Force and local security forces. A central committee was established, comprising representatives from the Delhi Police, Central Industrial Security Force (CISF), Airports Authority of India (AAI), Bureau of Civil Aviation Security (BCAS), and the Air Force.

Although the pilot later informed ATC that the alarm was a false signal, security protocols remained in effect. A former ATC official explained, “The ATC cannot ensure that the pilot isn’t under duress when declaring the situation as safe.”

At around 9:30 PM, Mumbai airport authorities activated full emergency procedures. They formed an aerodrome committee and deployed local police alongside National Security Guard (NSG) personnel. The aircraft eventually landed in Mumbai at 9:47 PM and was directed to an isolation bay for security checks.

Emergency Situation Triggered by Transponder Code

The Air India flight’s transponder sent a critical emergency code “squawk 7500” to Delhi ATC for three minutes right after takeoff. This code specifically indicates unlawful interference or hijacking, prompting immediate action from multiple aviation authorities.

Aviation systems use transponder squawk codes, ranging from 0000 to 7777, to identify individual aircraft. Among these codes, 7500 signals potential hijacking, while 7600 indicates radio communication failure and 7700 denotes general emergencies.

The incident has initiated a thorough investigation involving the Directorate General of Civil Aviation (DGCA), BCAS, and CISF. Officials aim to determine whether the false alarm resulted from pilot error or misinterpretation by air traffic control.

False Hijack Signal Investigated

Preliminary investigations suggest that crew involvement in the false hijack signal is unlikely, with a technical error emerging as a possible cause. The pilot promptly notified Delhi ATC about normal flight operations after discovering the erroneous signal. Despite this, security protocols were maintained throughout the flight.

Upon landing, the pilot reassured authorities that the flight had operated without any security threats. A ministry official emphasized that emergency protocols must remain in force following a hijack signal activation, underscoring the aviation industry’s commitment to strict security measures.

Rising Concerns Over Security Threats

The Ministry of Civil Aviation reported an alarming 999 hoax bomb threats targeting airlines between January and November 14, 2024, with a staggering 666 occurring in October alone. In response, the ministry has amended the Aircraft (Security) Rules, 2023, introducing hefty fines of up to ₹1 crore for false security threats.

New regulations establish penalties for individuals and organizations that provide misleading information that jeopardizes flight safety or incites panic among passengers. The Bharatiya Vayuyan Vidheyak Act 2024 has replaced the Aircraft Act of 1934, categorizing most violations as non-cognizable offenses, which require court permission for FIR registration.

Conclusion

The incident involving Air India flight AI2957 highlights the critical importance of aviation security protocols and the swift response required in the face of potential threats. As investigations continue, the aviation community remains vigilant, ensuring the safety of passengers and crew alike.
