RE: F-4E with Slatted wings?
Harry,
John is right on this one. I got to fly a soft wing E a few years back and as part of ground ops you drive the slats to the out position to check them. I may have a pic somewhere. Additionally it made it hard to pull to a known G of five or so because just as you'd get to 5 G, the slats would deploy and slap another G on quick.
