I know there is a belief that Rust/Ada etc is safer than C/C++ and in some cases that is true. I know of multiple, airworthy aircraft that are flying with C++ code. I also know of aircraft flying with Ada. The aircraft flying with Ada is hard to maintain. There is also a mountain of testing that goes into it that is not just unit testing. This mountain of integration, subsystem and system level testing is required regardless
