The F-4 landing chute could be repacked by most anyone and we used them often to save the brakes. It took a stand and a good wacking with a chock to get all of that JP stinking nylon into the tailcone. It was deployed by a large spring.
Well you didn't *always* need to use a chock as those rascally PCs made me use my fist to punch the last of the chute into that little tailcone - of course racking my knuckles in the process!
