Narrative:
ATC cleared air carrier X to immediately climb to 17000 ft -- acknowledged. Climb power set, rotation out of 10000 ft commenced. ATC instructed us to level at 10000 ft immediately. Pulled power back and initiated 1.5 'G' push to stay level at 10000 ft. Air carrier Y passed directly overhead at 11000 ft.
