Thank you to @StephenM for his leadership in advancing the release of additional UAP records through the PURSUE initiative. Each release is essential for understanding the nature of UAP.
My strategic goal as the @UAPSAC chair is to collect higher quality data in the future by deploying new sensors in partnership with the Pentagon. My gratitude goes to @rosscoulthart for supporting this data collection initiative in his recent comments on the Reality Check podcast. In the coming years, we might be surprised not only to find out that humans are not at the top of the cosmic food chain, but also that many forms of dark alien technology were undetectable by the sensors that we employed to search for them.
This weekend, I will have the privilege of participating in the hybrid live event “We Interrupt This Program” at the historic Virginia Theatre in downtown Champaign, Illinois. The “Show” is an original satirical play written by four-time Emmy winner Bill Odenkirk. The “Tell” is a live, panel discussion moderated by Emmy-winning PBS host, Sarah Edwards.

Manuscript updated. We found seven more beating objects in four PURSUE videos. This is starting to feel like a Hitchcock film...

Unresolved UAP case now explained by the @UAPSAC. DOW-UAP-PR135 was released in PURSUE tranche 6.
We show that the six objects flicker at wingbeat rates. The reported high speeds are the parallax effect. Bird is the word.

On Fox News, former UAP Task Force Director, Jay Stratton, was asked, "Does the government have non-human craft in its possession?" He answered, "Yes, it does."
I want to see evidence beyond a reasonable doubt that UAP, are linked to non-human technologies. After meeting Jay, I invited him to speak with the UAP Science Advisory Council. Jay did not respond to my invitation. Why is it a higher priority for Jay to speak with Fox News than with the @UAPSAC council?
Are We the Indigenous Intelligent Species in Our Cosmic Neighborhood? My discussion last night with @jessecordweber
The claim made in this post is false and does not accurately represent my views or scientific work.
The search for signs of extraterrestrial technological civilizations is a serious scientific endeavor. It deserves to be discussed with intellectual honesty, scientific rigor, and respect for the evidence.
I have seen and heard from many people who are understandably frustrated when my words are taken out of context, distorted, or used to promote misinformation. I understand their frustration and share their concern.
My effort to popularize the scientific search for non-human intelligence and extraterrestrial technology requires that I communicate directly with the public. Going forward, this will also include publicly correcting those who misuse my name, misrepresent my statements, or attribute claims to me that I have never made.
Science advances through evidence, not misinformation. I welcome criticism and scientific debate, but they must be based on what I actually say and do.
Also, I want to thank the many people who continue to support my work and the scientific search for extraterrestrial technology. Your encouragement, curiosity, and positivity provide me with tremendous motivation to continue this important effort.
The universe is vast, and there is much left for us to discover. Let us focus on finding the truth.

My thanks to @GarryPNolan, Peter Skafish, and @uncertainvector for pushing the frontiers of what we know and expanding the boundaries of scientific inquiry, and to Lyn Lear and @PeterDiamandis for hosting and fostering such an open and wonderful discussion.
NEWS: XPRIZE Chairman @PeterDiamandis is actively exploring the creation of a new XPRIZE for providing evidence of alien visitation.
Harvard astronomer @ProfAviLoeb tells me that the criteria under discussion would require a winner to demonstrate the existence of technology created by a non-human intelligence.
Loeb said he's identified a potential funder for the prize, but declined to name the person "until it's finalized."
The XPRIZE Foundation has become a major agenda-setter in the world of science. An XPRIZE about an alien presence in Earth's proximity would be a major milestone in the transformation of a once-fringe topic into a prestigious subject of scientific inquiry.
The potential prize was a focus of a UFO-centric salon that Diamandis hosted in Santa Monica this past weekend.
Co-host Lyn Lear, widow of Norman Lears, tells me that Diamandis and his foundation are "looking into" the creation of such a prize.

One of the distinguished guests I met two days ago told me that he recently heard from an official at the highest level in the Pentagon that the U.S. is in possession of alien technology and related biological material. Access to such materials will save time over the interpretation of fuzzy PURSUE videos.
In an interview tonight with Jesse Watters on Fox News, I stated that it is my great privilege to assist the Trump administration in figuring out the nature of UAP. If the U.S. government or its contracted corporations have a physical sample of UAP technology, its meticulous scientific analysis can easily demonstrate that it is technology of alien (non-human) origin by virtue of its material composition, structural complexity or technological capabilities and functions.
Thank you, Peter Diamandis, for graciously hosting me and an extraordinary group for a fascinating discussion about UAP and the future of scientific discovery. Peter and I share the view that ambitious questions deserve ambitious efforts. The time has come for an XPRIZE with a simple challenge: identify a technological object that was not made by humans. The search for Alien technology deserves an XPRIZE.
