Absolutely stressful, but those guys are not going to put their lives too far out on a limb.
The ride in a big ole blumber bus like that has to be unique. I would imagine it to be smoooooth, compared to a shaky, nimble fighter, designed for such a stunt.
This is putting a fighter to it's max. stress !! This gets wild at the 3 min mark.
Some of these maneuvers were a death knell only a few years back.
