I was standing right at the rope of the spectator line about 2500 feet down the runway, which was a bit closer to the plane than this camera was.
It didn't look nearly this hard in person! (cue the: that's what she said)
On this video I see a much harder landing than I saw in person. I think that the telephoto compression makes the crab angle look much greater than it really was. I was looking at it through a 200mm lens but the film camera for this video was much greater than that.
It sure did kick up a lot of dust though.
And as someone posted above, if they couldn't get it stopped by the taxiway they did, I think it was going to have to be towed backwards down the runway. Apparently it can't do a 180 on 36/18 so when it leaves Oshkosh it will be pushed back down the length of the runway and go from there.
One more thing. It only flew about a 2 mile final from a dog-leg base turn. So for a test pilot who may not have flown the thing much recently (I have no idea about that part though), and 10-20 knots of gusty wind from a 90 degree crosswind, there wasn't a whole lot of time to get it lined up.
