DoD became impatient in 1998 and directed the project manager to switch to C++. He dutifully obeyed and turned his lame cadre of Ada "engineers" into an army of feckless C++ hackers. The project is still in the toilet today. The original "senior" "Ada engineer" disappeared back into the hole from whence he had appeared.
Thankfully, my total involvement in that fiasco was just a couple project review meetings. Yuck. I'm not sure that I would be anxious to be an F-22 pilot.
