Would You Get Off the Plane?

There’s an old joke about an instructor who asks, “if you were on a plane, and found out that the inflight systems were controlled by a beta version of software written by your team, would you get off the plane?” Most of the students pale and say yes. One person says, “No. If it were written by my team, it wouldn’t make it to the runway.”

The implication is that most software is far crappier than people realize, and that programmers are keenly aware of this. But I’d like to present another reason for getting off the plane:

Even if my team writes good code, the fact that it’s still in beta means that it hasn’t been fully tested. That means that there must have been some kind of snafu at the airline and/or the software company for untested software to be put in control of a flight with ordinary passengers. And if management permitted this error, what other problems might there be? Maybe the fuel tanks are only half-full. Maybe the landing gear hasn’t been inspected.
