At a recent computer software engineering course, the participants were given an awkward question to answer:
"If you had just boarded an airliner and discovered that your team of programmers had been responsible for the flight control software, how many of you would disembark immediately?"
Among the ensuing forest of raised hands only one man sat motionless. When asked what he would do, he replied that he would be quite content to stay aboard.
With his team's software, he said, the plane was unlikely to even taxi as far as the runway, let alone take off.
