I was watching through my 20X80 binoculars. I saw the puff in the trail and thought something looked different and then thought that the solid rocket boosters shouldn’t still be under power and knew that something was wrong.
I remember that it got down to 30 degrees that morning at the Kennedy Space Center in Florida
I lived in Palm Bay and heard on the radio that there was lift off, walked out the door to see it explode. Very sad day, indeed.
