In a "modern" well thought out system, yes, by face curtain or seat pan handle, but I remember that one of our local Air Guard's earlier birds (forget which one, F94, F89, F102, EB57??) had some sort of squeeze handle arrangement just forward and below the armrests. I could easily imagine a first time flyer, startled by the boot in the pants from the afterburner, grasping those handholds "put there for you to hold on to". SURPRISE!!
Cheers,
