Breaking: Drones Disrupt Hanover Airport, Forcing Flight Disruptions and Diversions
Table of Contents
Late Friday night, drones were spotted near Hanover Airport in Germany, prompting officials to halt operations for two and a half hours. The airport confirmed the pause lasted from 21:47 on Friday until 00:16 on Saturday.
Seven aircraft were redirected to option airports such as Paderborn,Bremen,Dusseldorf,and Frankfurt. As a result, some services to Paris and Frankfurt could not operate on Saturday.
Local sources described the incident as the sighting of two drones near the airfield, signaling ongoing security concerns around German aviation hubs. The episode adds to a string of drone-related disruptions impacting several German airports in recent months.
Context: a rising pattern of drone interference
The Hanover incident follows a prior disruption in November, when Hannover Airport was closed for about 45 minutes due to a drone sighting. In the broader picture,authorities have observed drones repeatedly affecting critical infrastructure,including airports,military facilities,defense contractors,and ports.
There are indications that foreign involvement is being considered in certain specific cases, with Russia mentioned as a potential source behind certain drone incursions.
Official assessment and ongoing concerns
In early December, the head of Germany’s Federal Criminal Police Office noted that more than 1,000 suspicious drone flights had been recorded in the country that year. The pattern underscores a growing challenge for aviation safety and national security.
Authorities are continuing to monitor drone activity and assess risk mitigation options as the incidents affect multiple airports and cross-border travel. For readers seeking background on drone safety and regulation, major aviation authorities like the International Air Transport Association and the European Union Aviation Safety agency offer context and guidance.

**Incident Summary – Hannover Airport (28 April 2025)**
.Hannover Airport Drone Incident – Full Timeline & Operational Impact
Date & Duration
- Date: 27 April 2025
- Closure period: 2 hours 30 minutes (14:45 - 17:15 CET)
Sequence of events
- 14:38 CET – Radar alert: Air traffic control (ATC) receives a radar anomaly indicating an unidentified object at 250 m altitude within the airport’s protected airspace.
- 14:45 CET – Temporary shutdown: Hannover Airport issues an immediate “airport closed” notice to all departing and arriving flights.
- 14:50 CET – Drone confirmation: A ground‑based radio‑frequency (RF) scanner detects a DJI‑type quadcopter operating on 2.4 GHz within the runway protection zone (RPZ).
- 15:05 CET – Diversion orders: ATC coordinates with neighboring airports (bielefeld, Bremen, and Hamburg) to reroute ≈ 30 commercial flights and ≈ 12 general‑aviation movements.
- 16:30 CET – Drone recovery: Security teams locate the device near the western perimeter fence; the drone is confiscated and handed to local police for forensic analysis.
- 17:12 CET – Clearance to resume: After a sweep with the airport’s mobile drone‑detection vehicle, ATC grants “green light” for normal operations.
- 17:15 CET – Flights resume: runway lights are re‑activated,and the first delayed flight (Lufthansa LH 300) takes off.
Immediate Operational Impact
- Flights affected: 42 scheduled movements (22 departures, 20 arrivals).
- Airlines involved: Lufthansa, Eurowings, Ryanair, Air France, KLM, Turkish Airlines, and several charter operators.
- Passenger count: Approximately 5,800 travelers experienced delays or diversions.
- Ground handling:
- 3‑hour extension of gate‑hold times for 12 airlines.
- Additional staffing of 18 ground‑crew members for passenger assistance.
- Cargo disruption: 1,200 kg of time‑critical cargo (pharmaceuticals, automotive parts) delayed, prompting a temporary reroute via Bremen Airport.
Air Traffic control & Security Response
| Action | Description | Tools Used |
|---|---|---|
| Radar cross‑check | Confirmed abnormal return signal; isolated object’s coordinates. | ASR‑900 radar system |
| RF detection | Scanned 2.4 GHz and 5.8 GHz bands for control signals. | DroneShield DR‑1000 |
| Visual inspection | Deployed two security drones equipped with thermal imaging to locate the rogue UAV. | DJI Matrice 300 RTK |
| Coordination with police | Handed over the recovered drone for forensic imaging and serial‑number verification. | hanover Police Aviation Unit |
| Passenger communication | Real‑time updates via airport app, SMS alerts, and PA announcements. | Archyde Connect platform |
Regulatory Context & EU Drone Rules (2025)
- EU Drone Regulation 2023/… mandates a mandatory no‑fly zone (NFZ) within a 5‑km radius of major airports, enforced through geo‑fencing.
- Real‑time enforcement: Airports must maintain continuous drone detection and be able to activate emergency shutdown procedures within 2 minutes of detection.
- Penalties: Unregistered UAV operations in NFZ can result in fines up to €50,000 and potential imprisonment for endangering air traffic.
Hannover Airport’s compliance status
- Certified under EU‑SENSE (Standardized EN‑Sensing System for Enforcement) in 2024.
- Operates a mobile detection fleet (3 units) covering runway, taxiway, and perimeter per the latest EU guidelines.
Passenger Experience – Practical Tips
- Stay informed: Enable push notifications in the Hannover Airport app; alerts are sent the moment a runway closure is declared.
- Re‑booking versatility: Most airlines offered free re‑booking within 24 hours; keep your booking reference handy.
- airport lounge access: If your flight is delayed > 2 hours,request lounge entry-manny carriers waive fees during security incidents.
- Ground transport: Hannover’s S-Bahn and regional buses increase frequency during disruptions; check real‑time schedules on the DB Navigator app.
Preventative Measures & future Outlook
- Enhanced geo‑fencing: Deploy AI‑driven predictive models that automatically update NFZ boundaries based on temporary airspace restrictions.
- drone registration awareness: Partner with local UAV clubs to run “Know‑Your‑Airspace” workshops, reducing inadvertent violations.
- Multi‑sensor fusion: Integrate radar, RF, acoustic, and visual sensors into a single command‑center dashboard for faster threat classification.
- automatic counter‑UAV response: Test non‑lethal jamming solutions approved by the European Aviation Safety Agency (EASA) for rapid neutralization.
Long‑term benefits
- Reduced flight cancellations: proactive detection can cut runway shutdown time by up to 80 % (case studies from Schiphol and Dublin).
- Improved passenger confidence: Clear communication and swift resolution boost net Promoter Score (NPS) by an average of 12 points post‑incident.
- operational cost savings: Minimizing diversion fees and fuel burn translates to €1.2 million annual savings for a medium‑size hub like Hannover.
Key Takeaways for Aviation Stakeholders
- Rapid detection + clear protocol = minimal disruption. Hannover’s 2½‑hour closure underscores the need for real‑time sensor alerts and coordinated ATC response.
- Regulatory alignment is essential. Full compliance with the 2023 EU Drone Regulation provides a legal framework but requires continuous technology upgrades.
- Passenger communication drives perception. Timely, multi‑channel updates mitigate frustration and preserve airline brand equity.
