I believe the Kate is a modified BT-13.
The Zero's are modified T-6's
I remember the first time I saw them at Oshkosh back in the later 70's.
They did a great routine for the Warbird show. Including a B-17 coming in with one engine smoking and with only one main gear down. From what I remember The 17 (Texas Raiders) did touch down on the one gear for a touch and go! But that might have been wishfull thinking on my part. I can't really remember. Although, my brother has the family home movies from back then. I just can't remember if it shows.

Although I won't go on and on about it..... I just cannot stand those CAF tattoos.......YUCK!!!!!
He's talking about the CAF Logo that their required to have on all their planes now.
I think it's dumb too. Just takes away from the plane's beauty.
Yeah, I liked it when they were very small and under the small N-number under the stabilizer.
Also, in this PC world of ours, I prefered it when they were called the Confederate Air Force! It was just cooler sounding. Never thought anything weird of it. Stupid PC crowd.
