News anchor Jim Lehrer was working as a newspaper reporter for the Dallas Times-Herald, covering President John F. Kennedy's visit to Dallas on November 22, 1963. While waiting at Love Field airport for Air Force One to arrive, he asked a Secret Service agent if the bubble top would be kept up on the limousine during the parade - a decision that seemed inconsequential at the time:
"And the bubble top was on the car. I saw the Secret Service agent who was in charge of the Dallas office... and I said, 'Are you going to keep the bubble top on or off?'... He looked up to the sky – I’ll never forget this – he looked up at the sky and he said, 'Well, this rain has stopped,' and he hollered at another agent who had a two-way radio, and he said, 'Is it raining downtown?' And the guy comes back and says, 'No, it’s clear.' So, he then says, 'Take off the bubble top.'"
