French investigators to release interim report on Germanwings jet crashed by co-pilot

France's air accident investigation agency says it will release an interim report about the crash of Germanwings Flight 4525, amid lingering questions about why the co-pilot appeared to intentionally drive the plane into the French Alps.

The agency, known as BEA, will publish the report Wednesday. It announced the release after German newspaper Bild reported what it said were details from the report.

Prosecutors have said that co-pilot Andreas Lubitz deliberately crashed the A320 jet into a mountainside on March 24, while en route from Barcelona to Duesseldorf. Cockpit voice recordings indicate Lubitz locked the captain out of the cockpit, while data recordings indicate that he repeatedly sped up the plane as brought it down.

All 150 people aboard the plane were killed.
