Germanwings and its parent company, Lufthansa, are still reeling from the disaster. Senior managers are facing a barrage of questions about Lubitz and the company's policies.

Lubitz passed his annual pilot recertification medical examination in summer 2014, a German aviation source told CNN. An official with Lufthansa said that the exam only tests physical health, not psychological health. The company was never given any indication Lubitz was depressed, the official said, and if he went to a doctor on his own he would have been required to self-report if he had been deemed unfit to fly.

The company has already changed its rules following the crash to ensure that two crew members are in the cockpit at all times. Many other airlines have taken similar steps or been advised by authorities to do so.

More and more information is coming to light about the lives of the passengers and crew members on Flight 9525. They include Iranian sports journalists who had been working at covering a big Spanish soccer game between Barcelona and Real Madrid; a group of young students from a German town who were returning from a school trip; two successful German opera singers who had performed at a Barcelona theater; and an American mother and daughter from Virginia.

Most of the people on the flight were from Germany or Spain, officials have said. Searchers at the mountainside crash site are continuing with their precarious mission to recover the remains of the dead.
