Could Better Screening Catch Suicidal Pilots?

German prosecutors said Friday that the German co-pilot of the crashed Germanwings jetliner may have suffered from depression and even hid a doctor's note excusing him from work on the day of the crash. The reports immediately raised questions of how and when pilots are screened for mental illness —especially pilots of airliners filled with passengers who rely completely on the pilot and aircraft to keep them safe. Experts say while commercial pilots are screened for depression, schizophrenia and other mental illnesses, it's not regular or intensive. And they say that doesn't matter because it's almost impossible to predict whether someone who is seemingly healthy might suddenly break down.
