I first saw Fifi at an old Confederate Air Force show in 1976. The Great Lakes Branch of the CAF had finally acquired a flyable warbird, one of the old C-45s, which is a Twin Beech (IF I remember right) used as a spotter and a twin engine trainer, as well as a liaison aircraft. The whole rest of the CAF flew up here to Indiana to celebrate, AND to celebrate the Bi-Centennial. Fifi was the star of the show. I didn't get to go very close to her, but I was right under the end of the runway when she took off and circled several times. I had to leave so I wasn't able to see her land but it was a glorious sight. If I remember, it was one of the 1st fly-ins she'd attended after getting certified for flight and display.
What a magnificent aircraft!
