At 10,000 feet and 90 knots, the U-2 takes 60 pounds of force to roll the yoke over, and 150 pounds of force to push the rudder pedals to the floor. But still, the plane handles much like other solid, rudder-heavy airplanes I've flown, like the DC-3. At 130 knots, however, that starts to change. It's a real challenge to get enough rudder and aileron movement to get that 30-degree bank accomplished. And at 220 knots, the task is all but impossible. I put two hands on the yoke and turn, hard. No luck. I have my full body force leaning into the yoke before I get it to move.
