I'm glad this is happening, and it's shame it took so long - or was ever introduced, really. Stuff like this hurts the public's perception of science. Everybody knew this was bullshit.
There are about 28,000 flights in Europe every day of the year and about 1.2 cell phones for every European. I doubt I've been on a plane in the past 5 years where every passenger over the age of 15 didn't have a phone. I like to think that I'm pretty good about turning my phone off (to airplane mode at least), but I've still managed to forget once during the ~30 flights I've been on in the past 4-5 years. Extrapolate that out, and it's obvious that if a phone could affect a flight, we'd be seeing cases every day. Terrorists would sneak phones onto planes to take them down.
Your average Joe sees "science" being used to support limits on cell phones, they know they're bullshit, so the next time they hear another "science-based" bit of info that goes against their comfort, they'll just ignore it too. Why would they bother, "science" is just BS anyway.
