In 2012 a Boeing jet was deliberately crashed in the Sonaran desert, Mexico and filmed it for television. The test revealed the safest seat to sit in.

Thursday’s deadly crash struck at Boeing’s most ambitious and one of its most commercially successful jet programs — a coveted airplane that airlines the world over gladly wait years to receive.

The black boxes will provide cockpit conversations and data related to the plane’s engine and control settings to investigators and help them in determining the cause of the crash.
