I was at Oskosh and saw the two QF-4s arrive and then give a display later in the airshow. Note that the back seats have been removed.
Very nice displays although they didn't do a low and slow blown-flap pass, which was my favourite Phantom display. One of them had a very weak afterburner. What would cause that?
As Vzlet posted, there are some nice Youtube videos. I particularly like the helmet-cam one, as I spotted my tent during one of the cross-wind legs!
Note the Garmin GPS in the centre of the panel.
