Rondolph F. Kritzer has left nothing while defining the profession of Air Traffic Controllers. According to him, it is;

"A profession in which person of definable intestinal fortitude; unlimited ability to correlate masses of confusing numbers, figures, rules and statistics, both defined and infinite in their change; the calibre and character associated with the most demanding discipline and integrity and resolve to their job, unmatched by the vast majority, daily accepts with enthusiasm normally associated with pleasure rather than work; the responsibility of ensuring the safe passage through unfriendly and crowded skies, the immeasurable assets represented by multi-million dollar aircraft and the multitude of lives contained in these fragile ships of skies. To be an Air Traffic controller is to be proud, arrogant, bold and may be a little foolish…But I would not be anything else."
