Never been to Oshkosh, but as a youngster, we used to live directly under the approach path of runway 22 at Detroit Metro Airport, at about 5 miles out. I remember the big hubbub when the Concorde landed there back in the '80s. My dad found out when it was due to arrive, and we went out into our back yard and waited for it to fly overhead. It wasn't going supersonic, (of course) but it was still loud enough and had enough rumble to shake an already loose window in our garage, out. That first video took me right back!
