A young and talented black box analyst is on a mission to solve the reason behind the deadly crash of a brand new airliner.

Atrian 800

A mysterious crash occured in the Alps involving the latest design of Atrian. This airliner could match with "the two other designer" but the crash did 300 fatalities.
To give substance to this promising model, the director used sometimes Unidentified (CGI) Aircraft :

This cockpit is a mix of latest Boeing and Airbus layout but the glass cockpit linked to side-sticks is close to the Airbus philosophy.
We sometimes see what seems to be an Airbus A330 ...

This is more clearly sometimes ...

Several times, we can see drawing and painting of a double-deck airliner (but devoid of any Airbus or real airline markings).
