The link doesn't say anything that I didn't already say....the proprietary Radar, EW, Communications and Defensive applications are always built in ADA, Small Talk, etc. It tells you there is ADA. The rest, the flight controls, etc, they can be written in anything that your processor can quickly translate, C++ is for sure cheaper to maintain and abundant labor supply so it makes perfect sense. By the way, just for future reference, sites like Wiki and SourceForge or StackOverflow, are never credible for top secret projects like the JSF. In fact, people, per their visual demo can be writing their hearts out about how whatever demo they saw, actually "works", but its never the case. There is a reason its called top secret. Thanks
ADA or C++ does not hold any superiority in terms of programming ability over each other. They both are good high level OOP languages. IMO, Americans just choose ADA and then stick with it to utilize the pool of engineers and reuse resources they have developed over the years in their earlier projects. Pakistanis choose C++ because of readily available C++ experts in Pakistan (and abroad) and immense resources (libraries etc.) now available in C++.
