Having an RN license is like gold, especially if you are wanting to become an airline pilot. You will never go hungry or be broke no matter what happens to the airlines. As far as being fired from a hospital, no worries. Only dates of employment are given by employers. You will be one of the few pilots to go through your career worry free. Most of us have no back up plan like an RN license. What state are you in? NYC and California pay good money to per diem nurses and chances are your regional will have a NYC base. Good luck and feel blessed. I'd love to be in your shoes.
