Weeeellllll!!!. I'm amazed at all the comments!!. I have just returned from Oshkosh, was dead level with the touchdown point, video'ed it, consulted my video, and all I can say is that it sure as hell raised NO EYEBROWS AT ALL amongst us [experienced pilots, some of us]. It was only the next morning that someone remarked that it appeared a bit firm.
I, being right next to it, and in a good position to judge it, would describe it it as a perfectly normal crosswind landing!!!!! I'm sorry if I am re-iterating what other people have said, I haven't had time to read all the posts, but I was there, and it didn't arise any comment whatsoever!!!!
