If, like me, you are a bit skeptical that your cell phone, or even more unbelievable, your iPod might cause a problem on an airplane, IEEE has an article that attempts to explain the danger and point to specific annecdotes where electronic usage might have caused navigation problems, IEEE Spectrum: Unsafe At Any Airspeed?. While I’ll continue to turn my cell phone off, I still maintain that if my iPod is causing problems with the airplane’s electronics than we have much bigger problems with airplane electronics. I hope they are more robust than that.
