March is women’s history month and there is no shortage of good stories about amazing women.   “Flygirls” by Keith O’Brien portrays female aviation pioneers.   Memoirs by former first lady Michelle Obama (“Becoming”), senators Kamala Harris (“The Truths We Hold”) and Kirsten Gillibrand (“Off the Sidelines”), and judge Sandra Day O’Connor (“Out of Order“) talk about life in the public sphere.  Form PM Margaret Thatcher and Supreme Court Justice Ruth Bader Ginsberg are profiled in book and film (“RGB” and “Iron Lady“).  Biographies of Sally Field, Joni Mitchell, and Bunny Mellon portray women in the arts. “Women Rowing North” by Mary Pipher explores ways women  can cultivate resilient responses to the challenges of aging.
