John, once again you illustrate the problem with usenet. "on the fue"?
"spoiler deployed as a speedbrake"?

Seriously, the 102 and 106 certainly didn't have it deployed "forward
of the tail" and those are the airplanes you were involved with in the
FAT ANG. The 105 didn't have it "forward of the tail" and the F-16
among current equippage doesn't have it "forward of the tail" either. 

Some do. The F-15 certainly is forward and the F-111 was certainly
forward. 

As for "spoiler deployed as a speedbrake"--that doesn't happen on any
fighter type that I've encountered. Certainly some tactical aircraft
used spoilers, primarily as a design counter to adverse yaw, but none
with spoilers have a choice of control surface or speed brake
function. Airliners do. 

Tell me again about your fighter experience. 

Speed brakes on fighters are single function surfaces.
