Pickens writes "Today, when most people refer to Ada, it's usually as a cautionary tale. The Defense Department commissioned the programming language in the late 1970s but few programmers used Ada claiming it was difficult to use. Nonetheless, many observers believe the basics of Ada are in place for wider use. "We're seeing a resurgence of interest," says Robert Dewar, president of AdaCore. "The thing people have always said about Ada is that it is hard to get a program by the compiler, but once you did, it would always work." Ada's stringency causes more work for programmers, but it will also make the code more secure, Ada enthusiasts say. Last fall, contractor Lockheed Martin delivered an update to ERAM, the Federal Aviation Administration's next-generation flight data air traffic control system — ahead of schedule and under budget, which is something you don't often hear about in government circles. Jeff O'Leary, an FAA software development and acquisition manager who oversaw ERAM, attributed at least part of it to the use of the Ada, used for about half the code in the system."
