IN a mans world, Cheryl Dutta stakes a claim to the skies. And she wont have anyone cloud her belief. Quiet confidence has her pronounce: "Nothing is male-dominated any more."

A place teeming with well-built, uniformed men who thrive on a traditionally macho vocation. Men who fulfill boyhood flights of fancy to play tough sky-soldiers.
