A new Pentagon office set up to track reports of unidentified flying objects has received "several hundred" new reports, but no evidence so far of alien life. The All-domain Anomaly Resolution Office (AARO) was set up in July and is responsible for not only tracking unidentified objects in the sky, but also underwater or in space or potentially an object that has the ability to move from one domain to the next. The office was established following more than a year of attention on unidentified flying objects that military pilots have observed but have sometimes been reluctant to report due to fear of stigma. In June 2021 the Office of the Director of National Intelligence reported that between 2004 and 2021, there were 144 such encounters, 80 of which were captured on multiple sensors. Since then, "we've had lots more reporting", said anomaly office director Sean Kirkpatrick. When asked to quantify the amount, Kirkpatrick said "several hundreds". This May, Congress held its first hearing in more than half a century on the topic, with members expressing concern that " whether or not the objects are alien or potentially new technology being flown by China, Russia or another potential adversary " the unknown creates a security risk. So far, "we have not seen anything, and we're still very early on, that would lead us to believe that any of the objects that we have seen are of alien origin", said Ronald Moultrie, under secretary of defense for intelligence and security. "Any unauthorized system in our airspace we deem as a threat."
