In a study released on Thursday by two industry groups, the Airline Passenger Experience Association and the Consumer Electronics Association, as many as 30 percent of all passengers said they had accidentally left a device on during takeoff or landing. About 67 percent said they had never done this, always ensuring that their electronics were turned off. Four percent were unsure.

In another segment of the study, passengers were asked if they turn their devices to “off” when instructed to do so by the pilot. Although 59 percent of passengers said they do fully turn their electronics off, 21 percent said they often simply switch to “airplane mode,” which disables the main radios of a gadget. Five percent sometimes adhere to the rule. And others were either unsure or do not carry electronic devices on a plane.

Naturally, the FA's warning bothered me and I felt the need to explain myself. I signaled for her to come back and asked her to hang my coat. I then said this verbatim—

"I want you to understand why I was taking pictures. I hope you didn't think I was a terrorist. Here is my business card [offering her one]. I write about United Airlines on an almost-daily basis and the folks at United in Chicago are even aware of my blog."

She took my jacket but refused to take my business card saying, "No, that's okay," then saying, "I did not know that" after I explained my reason for taking pictures. I again emphasize, I took no more pictures.

For example, quality control becomes an issue when parts can be made by anyone with the right equipment. What guarantee is there that they meet the needs of a full-sized plane? Even more problematic is the open nature of the project: if people can modify the design files before producing them, what implications does this have for the airworthiness of the final result? In particular, who is responsible if something goes wrong, and someone is injured?

It's great to see open source methods being applied to ever-broader fields, but we also need to make sure that there are no high-profile disasters -- like open-source planes falling out of the sky -- that could set back the wider application of the idea for years.

• The Airborne Laser was a proof-of-concept weapon that could take out missiles (in flight!) by shooting a laser from a modified Boeing 747. It's not really a practical way to shoot down missiles, but the idea seems to pop up about as often as putting lasers on sharks. [url]

There is still a small safety argument that resonates. ... If something goes wrong—which is admittedly rare, but not unheard of—it is probably to the advantage of all involved that they're paying at least some attention to what is going on around them. As safety measures go, they don't get much cheaper or more inoffensive.

But the more important reason to preserve the current rules is a spiritual one. There is something to be said for not being transfixed by an electronic gizmo. These devices have encroached on almost every aspect of modern life. Even in places that should be sacrosanct—at the cinema or theater, for example—sporadic buzzing, bleeping, and illumination courtesy of pocket-sized gizmos is abundant. I freely admit, I'm no angel here. Many's the time that I've interrupted a romantic meal at Buffalo Wild Wings to investigate a surprising Buzztime answer.

Those brief stints in which we must turn off our machines—the few minutes between push back from the gate and the extinguishing of the seatbelt sign, and the corresponding blackout at landing time—are something almost unique in modern life. Those rare moments in which our entertainment must come from within, not without. This is a perfect time to reflect on the journey ahead or the trip just taken. An all-too infrequent opportunity to quietly contemplate the world we live in and our place in the universe. A brief calm juncture in our otherwise hectic lives.

I'm not sure I'm convinced that the 0.5 seconds it takes to drop a Kindle and start screaming is going to cost anyone their life in a plane crash, but at least Bright admits that's the "small" argument. Unfortunately the only thing that's "big" about his other argument is the ego it must have taken to make it. I too think there's "something to be said" for switching off your gadgets once in awhile, but I'm not about to tell anyone it's necessary for their spiritual health, and I fear declaring cinemas to be "sacrosanct" is a bit much.

But even if you subscribe to this school of thought in full—and are the type of person who isn't satisfied with turning off your own gadgets, instead needing to tell other people to turn theirs off too—what does any of this have to do with airplanes? Every time a new technological tool is adopted into a new part of the average person's routine, someone is out there complaining that it "encroaches" on our lives, and those people have yet to accomplish anything except making themselves look increasingly foolish as time goes on. Many of us still know at least one holdout who bizarrely refuses to even own a cellphone (but will gladly borrow them from others when the need arises), and regardless of whatever "spiritual" benefits they think they are reaping, it generally hasn't delivered them to nirvana. Just because airplanes happen, randomly, to be one of the places that people are forced to tear themselves away from their gadgets, it doesn't make them temples of the Luddite religion. Philosophical questions didn't enter into the inception of the FAA's ban, and they shouldn't enter into the debate about its future.
