UFO hearing key takeaways: cover-up claims and Pentagon denials

Witness made several startling allegations about the US government and UFOs, but doubts lingered over key testimony

In scenes that felt reminiscent of a science-fiction movie, the US Congress held a public hearing on claims the government is covering up its knowledge of UFOs.

Unsurprisingly, the hearing generated huge interest in the US and around the world as it heard from three key witnesses, including David Grusch, a whistleblower former intelligence official who in June claimed the US has possession of intact and partially intact" alien vehicles.
