ODF: sorry to hear about your spine. That well and truly sucks.
Yes of course the front & center is unmistakably a Christen Eagle, with it's very distintive rainbow scheme. The Christen Eagle was basically a homebuilt Pitts S-2A with a wide cockpit and no dihedral in the bottom wings.
It is quaintly nostalgic to remember when the kit came out, the FAA went bananas over a picture in a magazine, which showed all the bubble-wrapped parts - they thought it didn't meet the 51% rule, so Christen shipped the ribs unbuilt to keep the FAA happy. Fast-forward to today, when well-heeled customers fly to a homebuilt factory and watch for a week while pros build their "homebuilt". But, I digress.
I have flown a Christen Eagle precisely once. I was at an airshow, and the very gracious owner insisted that I fly his nearly-new Christen Eagle. Like a smile from a strange, beautiful woman, how could I turn that down?
So I jumped in, and checked myself out with a low-altitude sequence in it
Here's another hobby of mine: jumper dumping:
The photo was taken by the meat bomb in my front seat, who didn't have any belts on. Note the Soucy diamond starburst paint scheme. I am in right echelon. The yellow-and-black S-2C is flown by a friend of mine - Jimmy Buffett wrote songs about his adventures - in left echelon - same setup - and in the lead is a Guatemalan-registered 450hp Stearman.
How we dump the jumpers is drive over show center, smoke on, half roll inverted in a vic, and let gravity take the three meat bombs away. I really wish we could have had a 4th airplane with us, to take a picture of us inverted, with the meat bombs departing!
