Mineta Tale of Cheney and the Incoming Plane on 9/11

The story makes little sense from any perspective. For instance, if the orders were to shoot the plane down, why wasn't it shot down? If the orders were for a stand-down or not to shoot, wouldn't this be an incredible admission? Can anyone believe that Cheney would give such public orders to this effect?

Why exactly did Mineta resign the DAY AFTER this strange story was relayed on national TV, on Fox News by Jim Fetzer? Another strange coincidence?

Or is the story possibly just disinfo?

Interestingly, Mineta served as a military intelligence officer before being elected to public office.
