Los Angeles wildfires: Firefighting plane grounded for 3 days after drone strike causes 'fist-sized hole'

FOX News

Experts say saltwater isn't a fire department's first choice, but is sometimes necessary to battle out-of-control flames. Federal authorities and California police are investigating after someone flew a drone into the wing of a firefighting aircraft as it carried water to battle the raging wildfires across Los Angeles – causing a "fist-sized hole" and knocking it out of service for days at a crucial time. It happened as the plane, the Quebec 1 Super Scooper that flew down from Canada to help, was working to contain the Palisades Fire, a Federal Aviation Administration spokesperson told Fox News Digital. It was one of only two Super Scooper aircraft in use in Southern California at the time. Around 1 p.m. Thursday, a civilian drone flew into its wing, according to Los Angeles Fire Department spokesman Erik Scott.

Please do not pilot your drones over the deadly wildfires raging across portions of Southern California. None of the footage is worth grounding emergency response planes--or the potential jail time. The Federal Aviation Administration was forced to issue a reminder on January 9th, shortly after an unidentified civilian drone collided with a Canadair CL-415 Super Scooper at approximately 1PM PST over the Palisades firestorm. "Anyone who interferes with emergency response operations may face severe fines and criminal prosecution," the FAA also posted on Thursday evening to social media. "If you fly, emergency responders can't," they added, echoing a similar motto from the US Forestry Department.


Drone collides with firefighting aircraft over Palisades fire, FAA says

Los Angeles Times

A drone collided with a firefighting aircraft flying over the Palisades fire on Thursday, the Federal Aviation Administration said in a statement. The aircraft landed safely and the incident will be investigated, an FAA official said. "It's a federal crime, punishable by up to 12 months in prison, to interfere with firefighting efforts on public lands," the statement said. "Additionally, the FAA can impose a civil penalty of up to 75,000 against any drone pilot who interferes with wildfire suppression, law enforcement or emergency response operations" during a temporary flight restriction. "We hit a drone this afternoon -- first one," said L.A. County Fire Chief Anthony Marrone.


Diffusion Models for Smarter UAVs: Decision-Making and Modeling

arXiv.org Artificial Intelligence

Unmanned Aerial Vehicles (UAVs) are increasingly adopted in modern communication networks. However, challenges in decision-making and digital modeling continue to impede their rapid advancement. Reinforcement Learning (RL) algorithms face limitations such as low sample efficiency and limited data versatility, further magnified in UAV communication scenarios. Moreover, Digital Twin (DT) modeling introduces substantial decision-making and data management complexities. RL models, often integrated into DT frameworks, require extensive training data to achieve accurate predictions. In contrast to traditional approaches that focus on class boundaries, Diffusion Models (DMs), a new class of generative AI, learn the underlying probability distribution from the training data and can generate trustworthy new patterns based on this learned distribution. This paper explores the integration of DMs with RL and DT to effectively address these challenges. By combining the data generation capabilities of DMs with the decision-making framework of RL and the modeling accuracy of DT, the integration improves the adaptability and real-time performance of UAV communication. Moreover, the study shows how DMs can alleviate data scarcity, improve policy networks, and optimize dynamic modeling, providing a robust solution for complex UAV communication scenarios.


Path Planning for Multi-Copter UAV Formation Employing a Generalized Particle Swarm Optimization

arXiv.org Artificial Intelligence

The paper investigates the problem of path planning techniques for multi-copter uncrewed aerial vehicles (UAV) cooperation in a formation shape to examine surrounding surfaces. We first describe the problem as a joint objective cost for planning a path of the formation centroid working in a complicated space. The path planning algorithm, named the generalized particle swarm optimization algorithm, is then presented to construct an optimal, flyable path while avoiding obstacles and ensuring the flying mission requirements. A path-development scheme is then incorporated to generate a relevant path for each drone to maintain its position in the formation configuration. Simulation, comparison, and experiments have been conducted to verify the proposed approach. Results show the feasibility of the proposed path-planning algorithm with GEPSO.


Zero-shot Shark Tracking and Biometrics from Aerial Imagery

arXiv.org Artificial Intelligence

The recent widespread adoption of drones for studying marine animals provides opportunities for deriving biological information from aerial imagery. The large scale of imagery data acquired from drones is well suited for machine learning (ML) analysis. Development of ML models for analyzing marine animal aerial imagery has followed the classical paradigm of training, testing, and deploying a new model for each dataset, requiring significant time, human effort, and ML expertise. We introduce Frame Level ALIgment and tRacking (FLAIR), which leverages the video understanding of Segment Anything Model 2 (SAM2) and the vision-language capabilities of Contrastive Language-Image Pre-training (CLIP). FLAIR takes a drone video as input and outputs segmentation masks of the species of interest across the video. Notably, FLAIR leverages a zero-shot approach, eliminating the need for labeled data, training a new model, or fine-tuning an existing model to generalize to other species. With a dataset of 18,000 drone images of Pacific nurse sharks, we trained state-of-the-art object detection models to compare against FLAIR. We show that FLAIR massively outperforms these object detectors and performs competitively against two human-in-the-loop methods for prompting SAM2, achieving a Dice score of 0.81. FLAIR readily generalizes to other shark species without additional human effort and can be combined with novel heuristics to automatically extract relevant information including length and tailbeat frequency. FLAIR has significant potential to accelerate aerial imagery analysis workflows, requiring markedly less human effort and expertise than traditional machine learning workflows, while achieving superior accuracy. By reducing the effort required for aerial imagery analysis, FLAIR allows scientists to spend more time interpreting results and deriving insights about marine ecosystems.


EDNet: Edge-Optimized Small Target Detection in UAV Imagery -- Faster Context Attention, Better Feature Fusion, and Hardware Acceleration

arXiv.org Artificial Intelligence

Detecting small targets in drone imagery is challenging due to low resolution, complex backgrounds, and dynamic scenes. We propose EDNet, a novel edge-target detection framework built on an enhanced YOLOv10 architecture, optimized for real-time applications without post-processing. EDNet incorporates an XSmall detection head and a Cross Concat strategy to improve feature fusion and multi-scale context awareness for detecting tiny targets in diverse environments. Our unique C2f-FCA block employs Faster Context Attention to enhance feature extraction while reducing computational complexity. The WIoU loss function is employed for improved bounding box regression. With seven model sizes ranging from Tiny to XL, EDNet accommodates various deployment environments, enabling local real-time inference and ensuring data privacy. Notably, EDNet achieves up to a 5.6% gain in mAP@50 with significantly fewer parameters. On an iPhone 12, EDNet variants operate at speeds ranging from 16 to 55 FPS, providing a scalable and efficient solution for edge-based object detection in challenging drone imagery. The source code and pre-trained models are available at: https://github.com/zsniko/EDNet.


CloudTrack: Scalable UAV Tracking with Cloud Semantics

arXiv.org Artificial Intelligence

Nowadays, unmanned aerial vehicles (UAVs) are commonly used in search and rescue scenarios to gather information in the search area. The automatic identification of the person searched for in aerial footage could increase the autonomy of such systems, reduce the search time, and thus increase the missed person's chances of survival. In this paper, we present a novel approach to perform semantically conditioned open vocabulary object tracking that is specifically designed to cope with the limitations of UAV hardware. Our approach has several advantages. It can run with verbal descriptions of the missing person, e.g., the color of the shirt, it does not require dedicated training to execute the mission and can efficiently track a potentially moving person. Our experimental results demonstrate the versatility and efficacy of our approach.


UAV-VLA: Vision-Language-Action System for Large Scale Aerial Mission Generation

arXiv.org Artificial Intelligence

The UAV-VLA (Visual-Language-Action) system is a tool designed to facilitate communication with aerial robots. By integrating satellite imagery processing with the Visual Language Model (VLM) and the powerful capabilities of GPT, UAV-VLA enables users to generate general flight paths-and-action plans through simple text requests. This system leverages the rich contextual information provided by satellite images, allowing for enhanced decision-making and mission planning. The combination of visual analysis by VLM and natural language processing by GPT can provide the user with the path-and-action set, making aerial operations more efficient and accessible. The newly developed method showed the difference in the length of the created trajectory in 22% and the mean error in finding the objects of interest on a map in 34.22 m by Euclidean distance in the K-Nearest Neighbors (KNN) approach.


Learning-based Detection of GPS Spoofing Attack for Quadrotors

arXiv.org Artificial Intelligence

Safety-critical cyber-physical systems (CPS), such as quadrotor UAVs, are particularly prone to cyber attacks, which can result in significant consequences if not detected promptly and accurately. During outdoor operations, the nonlinear dynamics of UAV systems, combined with non-Gaussian noise, pose challenges to the effectiveness of conventional statistical and machine learning methods. To overcome these limitations, we present QUADFormer, an advanced attack detection framework for quadrotor UAVs leveraging a transformer-based architecture. This framework features a residue generator that produces sequences sensitive to anomalies, which are then analyzed by the transformer to capture statistical patterns for detection and classification. Furthermore, an alert mechanism ensures UAVs can operate safely even when under attack. Extensive simulations and experimental evaluations highlight that QUADFormer outperforms existing state-of-the-art techniques in detection accuracy.
