After the Asiana Airlines crash, you might be interested to watch this 1960 movie about a crash investigation. Peter Cushing is always great, and the other actors are equally good. You have to sit through a lot of talk - hey, it's an investigation - but they do make it interesting. Loosely inspired by the de Havilland Comet fiasco.
The presentation varies between widescreen and pan-and-scan, sorry, it isn't my fault.
Also known as Trouble in the Sky.
