As RF4 said, the Voodoo and Phantom had a ram air bellows that increased the aft stick force according to dynamic pressure. It was not "feedback", and only served to keep us from ripping the wings off if we pulled too hard too fast, heh heh.
gums, i have to object on that one concerning the F4.
I´ve flown more than 3000 hours in that bird in all flight conditions, and the feedback was like natural in all flight conditions from stall to Mach 2.2 (yes, the RF-4E was going that fast in clean configuration). The expierience of a bellows failure demonstrated well enough how vital this system was for flight. I speak out of first hand expierience here.
Wether the system is a pure mechanical one or a computerized one like in the concorde, is imho secondary to this discussion. It was deemed necessary for decades and serves well until today. Boing deemed something alike necessary for it´s newest models 777 and 787.
Note: I´m not intending to value A v B, i was only trying to answer Dani´s input concerning feedback in the last years.
