I worked on other aircraft using Ada (the C130J and the C27J) and we all used Ada - it was Ada83 and we sometimes shared some code with the F22 people. Ada was very successful on all those aircraft. By the way, the Boeing 777 was also done mostly in Ada as was the Rosetta spacecraft which has just recently achieved a comet rendezvous after a 10 year journey. Jerry
