Lurking, to answer your Q, the Reds do wear g suits. They didn't for quite a while with the exception of synchro, however after a few minor g-related issues, common sense prevailed and all the front-seaters now wear them.
Back seaters however do not get that luxury (whether ground crew or experienced FJ mates) - the argument re control column snagging is a little stronger there and back seat G-LOC is less of a concern...!
