Investigators brief Germanwings relatives on crash findings

French air accident investigators are briefing relatives of the people killed in last year's Germanwings crash on the results of their investigation.

Saturday's closed-doors briefings in Bonn and Barcelona come ahead of the release Sunday of French accident investigation agency BEA's final report.

Investigators have established that the co-pilot of Flight 9525 from Barcelona to Duesseldorf, Andreas Lubitz, deliberately crashed the plane into a French mountainside last March 24, killing 150 people. Lubitz had previously been treated for depression.

Christof Wellens, a lawyer for some victims' families, said they have questions about "how can such an ill pilot be in the cockpit, how is it possible that such an ill person gets a pilot license?"

He said "they have many questions and every answer is very necessary for the families."
