pilot

you are flying at night in fog, when suddenly the TCAS alarm system makes an alert: CLIMB, CLIMB NOW but it is too late. you see a beechcraft hit your wing. the 737 is still flyable, but damaged. you lost a bit of the wing and shrapnel was sucked into the right engine, destroying it. your plane is thrown into a 15 degree nose down attitude. copilot: pull up! the alarm system calls: sink rate. you are at 15000 feet. what do you do?
