The US Congress will hold its first public hearing on unexplained phenomena since the 1960s on Tuesday.

The hearing will focus on the contents of a June 2021 Pentagon report that showed navy pilots had reported over 100 unexplained aerial phenomena since 2004.

According to the report, 18 of the reported UAP occurrences displayed extremely unusual flight behaviors, with the mysterious objects appearing to remain stationary in winds aloft, move against the wind, maneuver abruptly or move at considerable speed, without any apparent means of propulsion.

9 things we learned about aliens in 2021.

Live Science reported that one piece of footage (captured by the U.S. Navy) appears to show a spherical UFO hovering in midair while bouncing from side to side, before plunging into the ocean. Luis Elizondo, a former Pentagon official, told the Washington Post that UAPs interfered with secret U.S. nuclear weapons facilities.

The congressional oversight committees have been looking into the claims since the New York Times and Politico reported on the Pentagon's secret research office. A public hearing is imminent.

Congress hasn't held a public hearing on unidentified aerial phenomena in over 50 years, but that will change next week when I lead a hearing in House. Americans need to be aware of unexplained occurrences.

There is a live stream at the public hearing. The U.S. representatives will question the Undersecretary of Defense for Intelligence and Security and the deputy director of naval intelligence about what they know about the unexplained phenomena.

Congress will hold a closed, classified hearing after this public hearing on the activity of the Pentagon group known as the Airborne Object Identification and Management Synchronization Group.

There are questions about whether UAPs could be satellites, belong to foreign governments or be fakes. If the experts still haven't ruled out an extraterrestrial explanation, representatives could ask them to give further details on the UAPs' potential methods of propulsion, along with any exotic material that could have been collected from them.

The AOIMSG was in the office. Secretary of Defense Lloyd Austin is advised on security matters by Moultrie, who has worked in senior roles in both the CIA and NASA. Bray works to provide intelligence summaries to the U.S. Navy.

The report didn't draw conclusions from the accounts, but it did say that there was no data to indicate any UAP are part.

The report is not the only one that the U.S. government has released. The US Sun made a Freedom of Information Act request in April that resulted in the release of more than 1,500 pages of documents. The document database was created by the Defense Intelligence Agency and included reports on more than 300 medical accounts of human interaction with aliens.

Tomorrow's hearing will give the public an opportunity to hear directly from subject matter experts, and leaders in the intelligence community, on one of the greatest mysteries of our time. The hearing would break the cycle of excessive secrecy and speculation with truth and transparency.

Not all of them were convinced. Arkansas Rep. Rick Crawford, the most senior Republican on the House intelligence subcommittee, questioned the focus on ufologists above other national security issues.

Crawford said that with China and Russia developing hypersonic weapons and the Biden administration leaking alleged US military operations in Ukraine, we have far more serious intelligence threats than flying saucers.
