The report states that NASA can play a prominent role in the broader government effort to understand UAP by leveraging open-source resources, technological expertise, partnerships, and assets to curate a robust dataset. It notes that the panel found no evidence that UAP are extraterrestrial in origin, but the limited high-quality data currently available prevents definitive conclusions about their nature. The study team recommends improving data collection through civilian and commercial sensors, better calibration of existing systems (including from pilots and air traffic control), and applying scientific methods rather than relying on anecdotal reports. It explicitly avoids reviewing specific past incidents and focuses on building a scientific framework, concluding that most UAP can likely be explained with sufficient high-quality data, while a small subset may require further investigation. No mention is made of crash retrievals, recovered biologics, or non-human intelligence.
