On July 21, 2025, a single military training flight turned a routine school day at Milestone School and College in Dhaka's Uttara neighborhood into one of the worst ground aviation disasters in modern South Asian history. A Chengdu FT-7BGI jet operated by the Bangladesh Air Force crashed directly into a school building housing hundreds of young students, taking 37 lives—including 28 children—and injuring over 170 others.
Twelve months after the tragedy, grief hasn't quietly faded into history books. It has turned into deep frustration.
Families of the victims and student activists across Bangladesh are asking why basic safety protocols failed so completely and why flying aging fighter jets over densely packed civilian neighborhoods was ever permitted in the first place. The tragedy wasn't just an unforeseen accident—it was a predictable disaster waiting to happen in one of the most crowded airspace corridors on the planet.
What Actually Caused the Milestone School Crash
The official report points to pilot error combined with immediate loss of control after takeoff from BAF Base Bir Uttom A. K. Khandker. Flight THUNDERCAT 701, piloted by a trainee on his first solo flight, entered an unrecoverable stall shortly after getting airborne.
Air traffic control advised the pilot to eject. At low altitude over a heavily built-up city, ejection meant leaving a runaway military aircraft to smash blindly into whatever lay beneath. The jet clipped the roof of Block 7 before crashing straight into the Haider Ali Building at 13:12 local time, right before a scheduled school break.
Flight Details: Chengdu FT-7BGI (Call sign: THUNDERCAT 701)
Takeoff Time: 13:06 BST
Crash Time: 13:12 BST
Fatalities: 37 total (28 students, pilot, ground personnel)
Injured: 173
The resulting fireball tore through the ground floor, trapping children in classrooms. Rescue operations were hindered by narrow roads and crowd congestion, forcing emergency services to improvise, including using Dhaka Metro cars to carry severely burned children to regional trauma centers.
The Core Controversies Families Are Fighting Today
It didn't take long for public grief to transform into widespread unrest. Protests broke out across Dhaka within 24 hours of the crash. A year later, families aren't satisfied with official condolences—they want systemic changes.
Disputed Casualty Numbers and Transparency
In the chaotic hours after the impact, conflicting death tolls released by various authorities sparked deep distrust. Families accused officials of minimizing the scale of the tragedy on ground. Student groups staged sit-ins and blockades demanding clear, unedited casualty registers and DNA-verified identification for all remains.
Urban Military Flight Corridors
Dhaka's population density sits at over 23,000 people per square kilometer. Conducting solo training runs with inexperienced pilots over high-density residential and school zones poses an obvious, extreme hazard. Urban planners and aviation safety experts had warned about military flight paths over Uttara for years.
The Use of Legacy Aircraft
The Chengdu F-7 series—a variant based on 1950s-era Soviet MiG-21 design—has long been criticized by defense analysts for high attrition rates. Protesters demanded the immediate grounding and retirement of all legacy trainer variants to protect both young aviators and civilians on the ground.
Why This Tragedy Sparked Political Aftershocks
This wasn't just another aviation crash. The public response hit a raw nerve in a country already navigating delicate political dynamics and high public skepticism toward state institutions.
When angry student groups confronted government advisers over casualty reporting, the standoff lasted eight hours. The resulting political fallout contributed directly to high-level leadership shakeups, including the removal of the Education Secretary following clashes between student protesters and security forces.
It showed that citizens were no longer willing to accept "mechanical fault" or "unfortunate casualty" as an excuse for administrative oversight.
What Must Happen Next to Guarantee Air Safety
If air authorities want to rebuild trust with grieving communities, passive inquiries aren't enough. Real reform requires concrete structural changes:
- Relocate Training Flight Corridors Immediately: Move all initial solo training flights and low-altitude maneuvers away from metropolitan centers like Dhaka to rural airbases with open flight paths over non-populated terrain.
- Accelerate Fleet Modernization: Phase out legacy aircraft variants like older F-7 jets in favor of modern, multi-redundant training platforms equipped with advanced fly-by-wire stability controls.
- Establish Independent Aviation Oversight: Remove internal military inquiries from isolated military jurisdiction. Civil aviation boards and independent safety investigators must participate in all ground-impact disaster reviews.
- Full Financial and Psychological Compensation: Provide permanent, legally binding stipends and long-term medical care for survivors living with life-altering burn injuries and trauma.
The memory of the victims at Milestone School shouldn't be reduced to a memorial plaque. Until flight paths change and obsolete jets are retired, the risk remains real every single time a military engine starts up over a crowded city.
