Bob Schieffer was a kid and saw Johsnon campaigning with a helicopter in 1948.
Helicopters were a new thing back then.
It was a great gimmick.
Johnson would throw his hat out of the chopper into the crowd.
Schieffer said that Johnson had an aide to retrieve the hat to return to LBJ.
LBJ would toss out dollar bills from a helicopter at his opponents rallies. He would land and leave a couple cases of whisky string there...
