On a plane bound for the Midwest from an East Coast city, a lanky 55-year-old woman sits in the 12th row window seat, knitting a sweater. Her waist-length, wavy white-blonde hair is held up in a bun behind her head by a pair of silver knitting needles, while another set clacks away at a gray top. Knitting is her way of keeping busy on this and the many other flights she must take for her unusual, and these days much in-demand job as a traveling abortion doctor, or as she puts it, a “fly-in abortionista.”
