Leaning Out - An Intimate Look at Twin Towers Engineer Leslie E Robertson (2018)

A man with a perspective like no other on the planet. The leading structural engineer of the World Trade Center oversees its construction, haunted by its fall ever since. A guru in high-rise design. Driven by his values as a pacifist and activist and the woman engineer who emboldened, expanded and ultimately saved the man she loved. About fulfillment, fragility, and a fighting spirit.
