Reliability dashboard

This dashboard provides transparency into real-world safety and reliability performance across customer operations. Data is updated quarterly with a one-quarter delay to allow investigations to complete and counts to stabilize.

From April through June 2026, the reliability rate improved by more than 50% compared with the previous quarter and improved by over 150% year over year. Technical Malfunction and Human Factors reliability rates improved substantially. Environmental Factor incidents increased, driven primarily by a rise in bird strikes during the spring months. A key driver of the technical and human-factor improvements was the broad adoption of our Cayley software release which has demonstrated significant reliability improvements from prior releases. Improvements were also driven by rapid growth in dock-based flights, which comprised nearly 50% of total flight volume and doubled quarter over quarter. Dock-based flights have shown a 3x higher reliability rate than controller-based flights, with some use cases exceeding this by a healthy margin. Our data continues to show that dock-based operations are the safest way to fly at scale.

Reliability Rate Breakdown:

Technical Factors

The reliability rate due to Technical Malfunctions improved by more than 50% compared with the prior quarter. Obstacle Avoidance failures remained the most common category, while software-stability improvements in Cayley and a higher percentage of dock-based flights drove most of the gains. In Q1, Cayley accounted for roughly 30% of flight volume; in Q2, it exceeded 90%. Cayley also addressed several emergency-landing triggers and added IMU sensor redundancy, mitigating in-flight sensor failures.

Human Factors

The reliability rate due to Human Factors improved by more than 70%. As noted above, this is heavily driven by increased dock usage, which avoids many of the risk factors of controller-based flights, but we are also seeing the impacts of improved automatic NightSense behaviors and reduced power draw. Most incidents still fall into two buckets: crashes after the pilot turned off obstacle avoidance, and damage during takeoff or landing. The vast majority of these incidents could be avoided by adhering to our recommended 10 ft of clearance for takeoff and landings and keeping obstacle avoidance on during flight.

Environmental Factors

The reliability rate due to Environmental Factors dropped by nearly 50% from the previous quarter. However, with only 14 incidents across nearly 400,000 flights, this factor is highly sensitive to small changes in raw counts. We saw a sharp rise in bird strikes causing 10 incidents, plus two additional confirmed instances of gunshot/air-rifle damage, and damage from extreme winds well outside our specifications.

Dock Landing Reliability

Dock landing success reached 99.91% by the end of the period. As before: most landings outside the Dock are not crashes; they are landings at safe alternate sites or next to the Dock, so designating safe alternate landing zones remains important.
