My mother-in-law is a therapist. She thought more than likely this gentleman is trying to get back to what he was before his tragic accident. I said his because all the others on that flight are deceased. His survivers guilt must be overwhelming. And before I get a bunch of replies about the family, friends & relatives of those deceased, I am not trying to mitigate their pain either. My point would be his attempt to return to his job is therapeutic for him. Whether he will be able to or not, it will be important for him to try. The "suits" will decide if he can ultimately.
