It’s a specific kind of quiet that follows a blast like that. People who were in Tavistock Square on July 7, 2005, don't usually talk about the noise first—they talk about the paper. Thousands of sheets of paper from nearby office buildings fluttering down like snow through a thick, acrid cloud of smoke. When we talk about a bomb on bus london, we aren't just talking about a mechanical failure or a movie scene. We are talking about the moment the 7/7 terror attacks shifted from a subterranean nightmare in the tunnels of the London Underground to a visible, daylight horror in the heart of the city.
The bus was a Number 30.
It was a double-decker, a Dennis Trident 2, operated by Stagecoach. It was heading from Hackney to Marble Arch, but it never made it. Because of the chaos already unfolding in the Tube stations at King’s Cross, the bus was diverted. It was packed. People who had been kicked off the trains, frustrated by "signal failures" and "power surges," hopped on the 30 thinking it was their lucky break to get to work. It wasn't.
The Morning the World Stopped
At 9:47 AM, nearly an hour after the three initial blasts on the London Underground, 18-year-old Hasib Hussain detonated a backpack full of organic peroxide-based explosives. He was sitting on the upper deck, right toward the back.

The explosion was devastating.
The entire upper deck was basically peeled away. It looked like a tin can that had been ripped open by a giant hand. Thirteen people died instantly on that bus. Many others were left with life-changing injuries, both physical and psychological. You've got to understand the context of that morning; London was already on edge. News was filtering out about "explosions" on the Tube, but the official word was still leaning toward electrical faults. The bomb on bus london changed the narrative instantly. It was undeniable. It was a coordinated attack.
Most people don't realize that Hussain actually tried to call his fellow attackers before he blew himself up. He was the youngest of the group. While Germaine Lindsay, Mohammad Sidique Khan, and Shehzad Tanweer had already completed their grim tasks in the tunnels, Hussain was wandering around King's Cross. He even went into a McDonald's. Think about that for a second. He sat there, bought a drink, and waited.
Why the Route 30 Became the Target
There is a common misconception that Tavistock Square was the intended destination. It probably wasn't. Because of the massive disruption caused by the three Tube bombs at 8:50 AM, the central London road network was a mess.
The Number 30 bus was diverted from its usual path. It was crawling through traffic. It reached Tavistock Square—right outside the British Medical Association (BMA) headquarters—and that’s where the bomb went off. It was a fluke of timing, but a lucky one if you can call it that. Because it happened right outside the BMA, dozens of doctors literally ran out of their offices to provide immediate triage. They used the building’s courtyard as a makeshift field hospital.
If that bomb on bus london had gone off two minutes earlier or later, in a more isolated stretch of road, the death toll might have been even higher due to a lack of immediate medical intervention.
The Explosives Used
The bombs weren't military-grade. They were homemade.
Specifically, they used TATP (Triacetone Triperoxide). It’s incredibly unstable stuff. It’s often called "Mother of Satan" because it can go off if you just drop it or if it gets too warm. The attackers manufactured it in a "bomb factory" in a flat in Leeds. This wasn't some high-tech operation funded by a nation-state; it was four guys with a backpack-sized grudge and some chemistry knowledge they'd picked up.
- The backpacks were large.
- They contained several kilograms of the mixture.
- The detonators were simple, likely using a basic battery trigger.
The Resilience of the City
London didn't just fold up and disappear after the 7/7 attacks.
Within 24 hours, people were back on the buses. Not because they weren't scared—everyone was terrified—but because they had to get to work. There’s this "Keep Calm and Carry On" trope that gets thrown around a lot, but in July 2005, it was a literal survival mechanism.
The investigation that followed was one of the largest in the history of the Metropolitan Police. They had to sift through thousands of hours of CCTV footage. They eventually tracked the four men back to Luton, where they had caught a Thameslink train into King's Cross. The image of the four of them entering the station with their backpacks is one of the most haunting pieces of footage in British criminal history.
Security Changes After the 7/7 Bombing
You’ve probably noticed that trash cans are rare in London stations now. Or that they use those clear plastic bags. That's a direct result of the era of bombings, though it actually started during the IRA campaigns. However, the bomb on bus london led to a massive overhaul in how the city monitors public transport.
- CCTV Integration: The bus network's camera systems were modernized and linked more effectively with central command.
- Radio Systems: The "Airwave" radio system was improved because, during the 7/7 attacks, emergency services actually struggled to communicate with each other underground.
- Public Awareness: The "See It, Say It, Sorted" campaign, while sometimes mocked for its repetitiveness, grew out of the need for the public to be the eyes and ears of the police.
Honestly, the way we travel today is fundamentally different because of what happened on that Number 30 bus. We are more observant. We look at unattended bags differently.
Remembering the Victims
It is easy to get bogged down in the tactics and the terror, but the heart of the story is the 52 people who died that day across all four sites. 13 of them were on that bus. People like Miriam Hyman, a 32-year-old picture researcher, or Shahara Islam, who was only 20. These were people going to work, people with lives and families.
The memorial in Hyde Park—52 stainless steel pillars—stands as a permanent reminder. Each pillar represents one of the victims. If you visit, you'll notice they are grouped by the location of the blasts. The group for the Tavistock Square bus stands as a testament to a morning that London will never truly forget.
What You Should Know Now
If you're researching the bomb on bus london for historical or safety reasons, there are a few things to keep in mind regarding how the city handles threats today. The threat level in the UK is monitored by MI5 and is currently "Substantial," meaning an attack is likely. This isn't meant to cause panic, but to explain why security is the way it is.
Actionable Steps for Modern Commuters:
- Trust Your Gut: If a bag looks out of place or someone is acting genuinely suspicious (not just "weird," but actually suspicious), tell a member of staff or a police officer. They would much rather deal with a false alarm than a tragedy.
- Know Your Routes: In an emergency, the main transit hubs are the first to close. Knowing secondary bus routes or walking paths in Central London is a basic safety skill.
- Official Sources Only: In the event of an incident, ignore Twitter/X rumors. Follow the Metropolitan Police (@metpoliceuk) or Transport for London (@TfL) for verified information.
- Emergency Features: Familiarize yourself with the emergency alarms on buses and trains. On a bus, the driver is your primary point of contact; they have a direct line to the control center.
The 7/7 attacks were a turning point for the UK. The bomb on bus london specifically showed that no part of the commute was "safe" from the threat of extremism at the time. But it also showed the incredible bravery of everyday Londoners—the doctors who ran toward the blast, the bus drivers who stayed with their passengers, and the millions of people who got back on a bus the very next morning.
If you want to look deeper into the legal outcomes, search for the "Coroner’s Inquests into the London Bombings of 7 July 2005." The 2011 report by Lady Justice Hallett provides the most exhaustive, factual account of every second leading up to and following the explosions. It debunks many of the conspiracy theories that floated around for years and provides the closure that many families needed.

Stay aware, stay informed, and remember that the history of London's transport is a history of resilience as much as it is a history of movement.
