I remember Arnold Palmer flying thru our control area (NAS Albany, GA) in the early 70’s. If I remember correctly, his call sign was NAP-1.
From the link (2011-02-01):
Palmer, 81, flew his Cessna Citation X from Palm Springs, California, back to his home in Orlando, Florida, on Monday, January 31, his last trip in the left seat. On arrival he announced that he would not renew his pilot certification, which expired that day.“I'll still be flying in my plane as much as always, just not in the cockpit," Palmer said. “Flying has been one of the great things in my life. It’s taken me to the far corners of the world. I met thousands of people I otherwise wouldn't have met. And I even got to play a little golf along the way.”
