The latest watchdog report on HMP Manchester is a masterclass in bureaucratic hand-wringing. The Independent Monitoring Board (IMB) is "disappointed" by the "little progress" made in stopping drones from dropping drugs and phones into exercise yards. They want more netting. They want more signal blockers. They want a bigger wall.
They are wrong.
The obsession with "stopping" drones is a fool's errand that ignores the basic laws of physics and economics. We are watching the state bring a knife—or perhaps a very expensive butterfly net—to a drone fight. The reality is that HMP Manchester, and the entire UK prison estate, is fighting a war against gravity and Moore’s Law. Gravity is free. Moore's Law makes the delivery system cheaper every single month.
If you think a few millions pounds of "anti-drone technology" will solve the contraband crisis, you don't understand the tech, and you certainly don't understand the market.
The Netting Fallacy
The most common "solution" proposed by observers is the installation of more netting. It sounds logical. If there is a net over the yard, the drone can't drop the package.
Except it can.
I have seen security teams spend hundreds of thousands on high-tensile wire mesh only to realize they’ve created a "catch-and-retrieve" system for the inmates. Modern drone pilots aren't just hovering and dropping; they are using magnetic release hooks and specialized delivery lines. If a package lands on a net, it stays there until an inmate with a long pole or a modified hook brings it down.
Even worse, netting creates a massive maintenance liability. In the damp, windy climate of Manchester, these nets sag, collect debris, and eventually require structural repairs that cost more than the original installation. Meanwhile, the drone pilot just flies to a different window or a different section of the roof.
The Physics of Failure
The watchdog complains about the lack of "technological solutions." This is code for signal jammers and geo-fencing. Here is the technical reality that the IMB won't tell you: jamming is a legal and logistical nightmare.
To effectively jam a drone frequency ($2.4\text{ GHz}$ or $5.8\text{ GHz}$) without interfering with the surrounding city’s Wi-Fi, emergency services, and legal communications is almost impossible in an urban environment like Strangeways.
Even if you deploy localized jamming, you are fighting a losing battle against autonomous flight.
- Standard Drones: Rely on a radio link. Easy to disrupt if you don't mind the collateral damage.
- Autonomous Drones: Use pre-programmed GPS coordinates or visual inertial odometry (VIO). They don't need a signal to fly. They don't care if you jam the radio waves. They follow a mathematical path, drop the payload, and return home.
You cannot jam a pre-programmed flight path without spoofing GPS signals, which is a federal-level intervention that carries the risk of downing a medical helicopter or a commercial flight nearby. The "tech solution" doesn't exist because the environment won't allow it.
The Economics of the Air
Why are drones winning? Because the ROI is astronomical.
A consumer drone costs £500. A single delivery of high-purity spice or a stack of iPhones can be worth £10,000 to £20,000 inside the walls. Even if the drone is seized on its first flight, the operation has a 2,000% profit margin.
The prison service is trying to use "denial" strategies against a "saturation" market. For every drone the authorities seize, the gangs have ten more in the trunk of a car. You are trying to build a wall against the wind.
The IMB report points to "slow procurement" as a hurdle. It’s not slow procurement; it’s the fact that by the time the Ministry of Justice signs a contract for a specific anti-drone sensor, the drone manufacturers have already released a new firmware update that bypasses it.
The Wrong Question
The public and the watchdogs keep asking: "How do we stop the drones?"
This is the wrong question. It assumes the drone is the problem. The drone is just a medium. Before drones, it was "throw-overs" in tennis balls. Before that, it was corrupt staff. Before that, it was the "social visit" handoff.
The real question is: "Why is the demand for contraband so high that a drone delivery is a viable business model?"
The watchdog notes that HMP Manchester is overcrowded and understaffed. When prisoners are locked in cells for 22 hours a day with no purposeful activity, the demand for drugs skyrockets. When there aren't enough officers to conduct proper cell searches or monitor the perimeter, the "risk" side of the gang's ledger disappears.
We are spending millions on "electronic shields" to cover up the fact that the internal security of the prison has collapsed. A drone can't deliver to a cell if the window is properly barred and the prisoner is engaged in a workshop. A drone drop in a yard is only successful if the inmates have the freedom and the time to coordinate the pickup.
The Brutal Truth of the Perimeter
I’ve walked perimeters where the sensors were "state-of-the-art." They go off every time a bird flies by or the wind hits a certain speed. Eventually, the staff suffers from alarm fatigue. They turn the sensitivity down. They stop looking.
The "contrarian" fix isn't more tech. It's more friction.
- Hardened Windows: Most drone deliveries aren't to yards; they are to specific cell windows where bars have been thinned or removed. Replace the Victorian-era iron with modern, integrated polycarbonate glazing that is impossible to pass a string through.
- Internal Intelligence: You don't stop the drone in the air; you stop the recipient on the ground. Use SIGINT (Signals Intelligence) to identify the mobile phones inside the prison that are communicating with the pilots outside.
- End the "Technology Shield" Myth: Admit that the sky is open. Focus on the last ten feet of the delivery, not the five miles of flight.
The Cost of the Illusion
By demanding "progress" on drone technology, the IMB is giving the government an easy out. It allows politicians to announce a £100 million "investment in security tech" which sounds great in a press release but does absolutely nothing to change the reality on the wings.
It is a massive transfer of wealth from the taxpayer to security contractors who know their products are effectively useless against a determined, low-cost aerial threat.
If you want to stop the drones at HMP Manchester, stop looking at the sky. Start looking at the cell doors. Start looking at the staffing ratios. Start looking at the fact that we are trying to run a 19th-century warehouse with 21st-century problems.
The drones aren't the crisis. They are the symptom of a system that has lost control of its own space. No amount of netting will fix a broken culture.
The sky isn't falling. It's already gone. Stop buying umbrellas and start fixing the house.
