Absolute classic. If you push away it is not a true representation of the race to break the sound barrier it is a fantastic representation of the race itself at the cost of lost pilots willingly risking their lives in the thing they love doing. The technology is simplified and incorrect in many ways but it goes unimportant as the movies blends the emotional cost weighs against the increasing technology to the extent you feel the pain in the drama. Ralph Richardson brilliantly plays his character making you wonder if he actually cares about the human cost or is just suppressing emotion in the way many people do. David Leans direction is excellent and it is a shame this film was not made in colour but an excellent film nonetheless. I have watched this film more than once which I dont do for a lot of films but many I do are David Lean's. Not his greatest film. But still a classic.
