By contrast, Ada is almost certainly the programming language used in the last airplane you flew, the last train you rode, etc.
By experience, I must unfortunately report that trains, cars, etc. use a mixture of assembly, C, C++, Java, C#... all the way to JavaScript
Of course, there are some safety measures: design and code reviews, extensive testing, etc. but they don't prevent, from times to times, horrible things to happen! See this...
As for the ARM discussion, it's illuminating, bring it on!
And my contribution to the language war: Java before they introduced all these bloating features, like generics, lambdas, etc. (So, that would be Java 1.6 or 1.7)
