I was a Crew Chief / Weapons Tech on the F4 Phantom C,D,E models in Udorn Thailand, made airmen of the quarter twice during my 4 year hitch there ( I loved it, kept extending my tour ), the reward was a 15 minute ride in the backseat if this flying death machine so I can relate, pilots main ambition when they have a "passenger" is to make you puke with barrel rolls, stress climbs, hang time ect, G suits will keep you from passing out but they do nothing to stop you from esophageal velocity discharge. When we closed up shop in 1975 I was re-stationed in Guam on B52 G's, got to ride in the NAV seat one of them as well, no rolls, tip turns or puking, more like a flying pencil with rubber wings
This was my bird 2 kills and lots of patches !!
