The AAS debacle was due to a lot of factors, IMO primarily requirements instability and failure to do any useful risk management. The FAA would do far better to procure and adapt ATC systems already in use in Europe or Canada (and readers of Dr. Feldman's periodic postings on non-DoD usage know what language _those_ are implemented in ;) than to start over from scratch in C or C++. As a taxpayer, I am apalled by the waste of money in starting over. As an airline passenger, I don't want the controller in the tower at Dulles to have his system crash while _my_ flight is in the landing pattern. Just about every common OO language, and especially Ada and Eiffel, are more appropriate for safety critical systems! -- -------------------------------------------------------------------------------- Michael Stark NASA/GSFC Phone: (301) 286-5048 Code 551 Fax: (301) 286-0245 Greenbelt, MD 20771 e-mail: michael.e.stark@gsfc.nasa.gov "I don't give them hell.
