Crowd Intelligence: How Aerial Drones Provide Real-Time Security at Major Live Events

When 53,000 runners and more than a million spectators converge on Chicago for the Bank of America Chicago Marathon, the live events security operation looks nothing like a fixed facility deployment. The threat environment moves with the course. The crowd surges, disperses, and reconverges across 29 neighborhoods and 26.2 miles of city streets. There's no perimeter to hold and no static position to defend. There's the course, the crowd, and however much of it any single security team can see at a given moment.
That's the fundamental challenge of live events security. The environments that attract the largest gatherings are also the hardest to monitor from the ground. Security teams are distributed across a wide area, working with radio communications and a partial picture of what's happening. Incidents can develop in seconds. Crowd dynamics can shift faster than any ground-based team can observe and respond.
Persistent aerial coverage changes what's possible. At events like the US Open and the Chicago Marathon, LandSkyAI's tethered drone systems provide continuous overhead situational awareness that no ground-level deployment can replicate. Here's what that looks like in practice, and why crowd intelligence has become a core layer of serious live events security programs.
Why Live Events Security Is Harder Than It Looks
The numbers behind major live events make the security challenge concrete.
The global crowd management and event security market reached $2.85 billion in 2024 and is growing at 17.1% annually. That growth isn't driven by optimism. It's driven by an incident history that makes the cost of failure obvious. In January 2025, more than 30 pilgrims died in a stampede at India's Kumbh Mela religious festival. In April 2025, a vehicle attack at a cultural festival in Vancouver killed 11 people. In August 2024, Austrian authorities arrested three individuals in connection with a coordinated plot targeting a Taylor Swift concert.
Each of these incidents shares a common factor: the threat materialized in a crowd environment where ground-level security had limited visibility into what was developing. By the time the situation was visible from the ground, response options had narrowed.
According to the National Center for Spectator Sports Safety and Security, 65% of event security directors say inappropriate fan behavior at their venues is worse than it was a decade ago. That statistic covers everything from altercations and alcohol-related incidents to the broader trend of events becoming harder to manage as crowd sizes grow and threat environments become more complex.
The security response to these environments has historically been to add more personnel. More guards, more checkpoints, more officers stationed at key locations. It's an understandable approach, and it provides real deterrence. But it doesn't solve the visibility problem. A security team distributed across a marathon course or spread across multiple event courts still has limited situational awareness of what's happening simultaneously, across the full event footprint, in real time.
That's what aerial coverage solves.
What Crowd Intelligence Actually Means
Crowd intelligence is a specific term for a specific capability: real-time aerial situational awareness that allows a security operations team to see the full event environment, monitor developing situations, and coordinate response before incidents escalate.
It's different from surveillance. Surveillance records. Crowd intelligence informs. The distinction matters because response time is everything at a live event.
When a crowd crush starts to develop at a finish line, it's visible from above before it's visible from the ground. Crowd density, movement patterns, congestion at bottlenecks — all of it is observable from an aerial vantage point that no ground-based camera or officer can match. A security operations team watching a live aerial feed can identify that a particular area is reaching dangerous density and redirect crowd flow before anyone on the ground has registered that there's a problem.
The same principle applies across every major event security scenario. A suspicious vehicle approaching a closed perimeter. An altercation developing near a stage. A medical emergency at a water station. An unauthorized individual working their way toward a restricted access point. Each of these scenarios is easier to detect from above than from the ground, and each has a response window that aerial early warning extends significantly.
At the Phoenix Police Department, deploying persistent aerial support reduced incident response times by 60%. That reduction isn't about having faster responders. It's about knowing where to send them, sooner.
Why Tethered Drones Are the Right Tool for Live Event Security
The tethered persistent aerial platform is the specific hardware that makes crowd intelligence viable at major events. Here's why the tethered model matters and what distinguishes it from free-flying drone operations.
A tethered drone is connected to a ground station by a physical tether that carries both power and data. Because it draws power continuously from the ground, the system can remain airborne for the entire duration of an event — no battery swaps, no operational gaps, no windows when the sky is empty. At an event that runs for eight, ten, or twelve hours, that continuity is operationally significant. A free-flying drone that needs to land every 30 minutes for a battery change creates predictable coverage gaps. A tethered system doesn't.
The tether also carries the video feed, which means the data is encrypted and physically secured in ways that wireless transmission isn't. For a live events security operation where real-time video is being fed to a command center, that matters both for security and for reliability.
Operationally, tethered systems deploy quickly and hold a stable aerial position even in moderate wind. They're designed to hover at a fixed altitude — typically 70 to 100 meters — providing a persistent overhead view of a defined area. A single tethered platform covering a finish line, a main stage, or a key congregation point provides continuous aerial intelligence of that environment for the full duration of the event.
For events with FAA Temporary Flight Restrictions — like the Chicago Marathon, which operates under a TFR that prohibits unauthorized aircraft within a two nautical mile radius of the course — tethered platforms have a different regulatory profile than free-flying aircraft. LandSkyAI holds the FAA authorizations required to operate within these restricted environments legally, which means the aerial coverage layer is available where and when it matters most, rather than being grounded by airspace restrictions that other operators can't navigate.
How LandSkyAI Deploys Aerial Coverage at the US Open and Chicago Marathon
Both the US Open and the Bank of America Chicago Marathon represent the operational complexity that serious live events security programs have to solve. They're both large-scale, high-profile events with different coverage challenges.
The US Open draws more than 700,000 visitors over its two-week run at the USTA Billie Jean King National Tennis Center in Flushing, Queens. The grounds-pass model means a large portion of daily attendance is moving freely between courts, concourses, fan zones, and public areas — not seated in one place. Multiple courts run simultaneously. The event footprint is concentrated but dense, with thousands of people occupying a relatively constrained area throughout the day and into the evening. The aerial coverage layer provides real-time situational awareness across the full grounds, with specific persistent coverage of high-density areas and key access points that ground-level positions can't monitor continuously.
The Chicago Marathon presents a fundamentally different challenge. The course runs 26.2 miles through 29 city neighborhoods. Spectator access is open along most of the course, with the largest crowd concentrations at the start corrals in Grant Park, at major landmark intersections throughout the route, and at the finish line on Columbus Drive. There's no fixed perimeter. Security operations have to account for an environment that spans the entire city. Tethered aerial coverage deployed at the finish line and key congregation points provides continuous overhead awareness of the environments where crowd density and threat potential are highest.
In both deployments, the aerial systems feed live video to a security operations center where trained observers are monitoring the event environment in real time, coordinating with ground teams, and providing early warning for developing situations. The aerial layer doesn't replace the ground security operation. It gives it eyes.
The Coverage Scenarios That Matter Most at Live Events
Crowd intelligence is most valuable in the specific scenarios where ground-level visibility breaks down. Here are the situations where aerial coverage changes outcomes.
Crowd density and crush prevention. Crowd crush events develop quickly and are difficult to detect from the ground until they've already reached a dangerous threshold. From above, crowd density and movement patterns are directly observable. Security operations teams watching an aerial feed can identify developing congestion at bottlenecks, stages, or exit points and initiate crowd flow adjustments before the situation becomes dangerous.
Perimeter and access control. At events with defined security perimeters, continuous aerial surveillance of the outer ring provides early warning of unauthorized access attempts that ground positions might not see. At events like the US Open with extensive grounds, aerial coverage of access points supplements the checkpoint infrastructure with an overhead layer that's harder to circumvent.
Medical and incident response. At a marathon with 53,000 runners, medical incidents are a statistical certainty. A runner who collapses at mile 18 on a city street is hard to locate from a command center relying on radio reports. An aerial system watching the course can locate the incident and guide response teams to the exact position in real time, cutting the gap between the event and the response.
Threat detection and tracking. Suspicious behavior, unauthorized vehicles, or individuals attempting to access restricted areas are observable from above in ways that ground surveillance often misses. Aerial tracking of a developing situation provides response teams with real-time location information as they move toward it.
What Live Events Security Looks Like With Crowd Intelligence
Event security directors who've added persistent aerial coverage to their programs describe the same shift: the event stops being a collection of discrete ground positions and becomes a single, continuously visible environment.
The finish line is no longer the point where you find out what went wrong. Crowd density at key areas is monitored in real time, not estimated from radio reports. Incident response is guided by live aerial video, not fragmented communications from distributed ground teams. And the documentation layer, continuous, timestamped, overhead footage of the full event environment, supports every post-event review, incident investigation, and law enforcement coordination that follows.
Live events will keep getting larger, higher-profile, and more complex to secure. The security infrastructure has to keep pace. Crowd intelligence, delivered by persistent aerial systems that provide continuous overhead situational awareness, is the coverage layer that makes that possible.
