Kennedy had authorized a squadron of U.S. aircraft to assist with the invasion by escorting the charge ’s B-26 wedge .

The reason why the escorts had evidence up belatedly ? The CIA and the Pentagon did n’t realize that there was a clock time zone difference of opinion between Nicaragua , where the escorts had left from , and Cuba .
