Congress decides what gets presented to it.

Did anyone even ask about larger radar tracks for this "UFO"?

A Hellfire masses less than 50kg. A Tomahawk cruise missile, for example, weighs over 1000kg. The impact is clearly glancing - the Hellfire retains much of its own speed.

Again, why would a hellfire missile ever be launched at a tomahawk cruise missile? Do the Houthis have tomahawks all the sudden? And this still does not answer why the pentagon would not comment or why this detail was not made available to Congress.
