Bush Airport Evacuated After Improvised Explosive Device Found on 9/11 Anniversary
On September 11, 2026, a routine day at Bush Airport was disrupted by the discovery of a live improvised explosive device. The incident, which occurred on the 25th anniversary of the 9/11 attacks, led to a significant police response and extensive searches across the airport terminals. A custodian found the device while performing his duties, highlighting a serious security concern.
Discovery of the Device
The discovery was made around 4:30 p.m. by a custodian emptying a waste bin in a men’s restroom near Gate D2. The device was described as a red cardboard tube, approximately 4 inches long and 1 inch in diameter, with a fuse attached. Initial examination by bomb technicians using X-rays revealed powder inside, the identity of which was not immediately known.
Device Analysis and Classification
Further testing confirmed the presence of a potassium chlorate mixture within the device. A bomb technician classified the substance as “violently energetic.” The technician’s report detailed that ignition would result in “a loud report, smoke, and a pressure wave as the container ruptured,” leading to the conclusion that it was, by definition, an improvised explosive device.
Initial Response and Escalation
The initial police call slip described the object as a “cheap firecracker.” However, the situation escalated when a captain at Houston Fire Department Station 63 refused to accept the device, citing the potential danger to the station. This refusal prompted the request for the bomb squad. A bomb technician later collected the object in a nearby field and transported it to the department’s tactical operations building for examination. Aviation security experts noted that the responding officer should not have handled or removed the device from the terminal, warning of potentially catastrophic consequences.
Airport-Wide Search and Timeline
A significant delay occurred in the response, with more than six hours passing between the initial discovery and the issuance of clear instructions for airport-wide searches. Once initiated, explosive-detection dogs swept Terminals A through E, baggage claim areas, the underground train tunnel, and loading-dock dumpsters. These extensive searches, covering both passenger and operational areas, did not uncover any additional devices.
Investigation and Security Review
Investigators reviewed surveillance footage to narrow down the timeline of the device’s placement. They determined that the custodian had cleaned the restroom earlier in the day, around 2:06 p.m., and had emptied the same bin. This left open the possibility that the device was placed after the initial cleaning or was somehow missed. The Houston Airport System referred inquiries to the police department, which stated that its investigation was ongoing. The agency affirmed its commitment to reviewing its response procedures to ensure they remain safe, effective, and efficient.
