“I watched the story that night on the evening news. The blackout episode helped me better understand what was ahead of me. I had been cautious. NSA was a national treasure and my first task had been to do no harm. Now it was clear to me that no course of action I could set out on would be as dangerous to the agency as standing still. Had I known what awaited me and America a year and a half down the road, I might have been even bolder. But the broader lesson stuck: caution isn't always a virtue, not if you're serious about doing your duty.”

“Look wide, and even when you think you are looking wide — look wider still.”

“The Air Force loathed everything about the AX, which soon would be known as the A10. Jokes were made that it was so slow that it suffered bird strikes, from the rear. And that instead of carrying a clock the cockpit had a calendar. The aircraft was so ugly it was called the ‘Warthog’. Many in the Air Force said no airplane could perform or survive in combat as this airplane was supposed to perform. It would be almost twenty years before the A10 had the chance to demonstrate just how wrong its detractors were.”
