Narrative:
We received pop-up TA from our TCASII 500 ft below, 12 O'clock, 2 1/2 mi. I looked out to see a U2 in a steep climb, 12 O'clock opposite direction. I took the controls and rushed over. The U2 passed 100 ft over us. I queried the controller who then started yelling at the U2 pilot. The controller told us he was on the wrong squawk code and altitude.
