The Late Famous Broadcast Journalist Walter Cronkite Said That One

question 154

True/False

The late famous broadcast journalist Walter Cronkite said that one of his regrets in life was not actively participating in the space program as an astronaut. Back in the 1980s, he was selected as a candidate to be the first journalist to fly into space, but NASA decided to take a teacher instead. In some ways, this may appear as though Cronkite was pursuing a self-esteem need; however, having already achieved celebrity status, for Cronkite, this was the pursuit of a self-actualization need.
