Good article. Again, no documentation that the device was definitively proven to be the actual cause of
 a problem. Even then, none of those problems actually resulted in an "incident" jeopardizing life or safety. There were cases that they were the SUSPECTED cause, based on some cursory tests by flight crew at the time of occurrence, but subsequent testing by trained technicians were unable to duplicate the problem. In some cases the device MAY have been a contributing factor, but not necessarily the specific cause of the anomaly. Regarding the situation of cellphones affecting ILS, the report concludes that the chance of that actually happening is one in one million, or POTENTIALLY once every two years in normal U.S. flight operations. Besides, all commercial aircraft systems have some kind of redundancy. A failure or inaccuracy of the ILS system is backed up by something, greatly reducing the likelihood of a crash due to that one issue. Being involved with various airfield operations over the years (twenty three years in USAF Communications), I have seen various ILS failures occur during landings. None of them resulted in a crash.

I have yet to find any documentation anywhere of a crash officially or otherwise caused by cellphone use. The one possible case was a small plane crash near Denver, where a Go-Pro camera mounted on the dash documented the pilot taking selfies with his phone just prior to losing control and crashing. While there are a few studies claiming the potential MAY exist for cellphones to interfere with navigational equipment, there are no documented cases of it actually happening.

Au Contraire... (or however you spell that crazy French word -- I just know English and Spanish ;-):

If you trust Boeing as somewhat of an authority on commercial airlines, read the following that's posted on their website ...
