Gig=did; Also there are ADA/C++ cross compilers. I know some of the people on the F22. It is going well this is just the usual caring. They are just rolling out the production bugs, the problems are mostly on the targeting acquisition system and some avionics integration issues, this process started less them 3 years ago. The "image" (as in radar) recognition system is having some problems. This is not unusual. The software architecture is wonderful and the avionics world is plenty of good ADA people, It is not a very hard language to learn, Real time concepts applied ot avionic is what is difficult. These isyems have there own Air Force/vendor "operationg systems" (perhaps morw aptly called "operating environments") it is unclear how whiching to another language is helpful
There is a real anti-f22 lobby, and it seems to originate in the Democrat party, at least in the US. The f22 is revolutionary and gives us an amazing edge over any other Air Force. Some people really do not want this. It will be fine if the program is allowed to go ahead.
