Don't forget to depressurize first, BEagle. I thought the canopy limit was 80kts but my F-4E manual says 'Canopy open, Ground Operation 60kts; Load Factor Not Applicable'!!! I don't have an RAF one. 60kts was, as you know, off the bottom of the clock by some 20kts! I'm sure some RAF types had emulated this feat in the early Coningsby days, presumably off a very low speed bunt. I don't think one needed to unstrap to do it, either, as I could certainly reach the front of the windshield .............. on the ground, of course.
