I've done the altitude training and barochamber ride at Beale AFB where U2 and some Global Hawk are based. U2 pilots provided some of the training and we were lucky enough to get a tour of a U2 and Global Hawk by a U2 pilot at the end of the day.

Most of the class were power pilots and some folks from aerospace contractors who required a chamber ride sign off. The U2 pilot described the roll out and ground handling attributes of the U2 and commented it can be a handful... like flying a glider. That got a smile out of the glider pilots present.
