Yes because the risk is more real. In theory - my knowledge of the problems we had making the obsolete GR2 Tornado's radar work would have been useful to the Russian IF there had been a WWIII, and if they didn't already know. And that the East Germans might have passed it on if I had been silly enough to carry all my technical reports with me to Berlin in the 80s But my current phone has a list of all the calls/emails to my company's component suppliers and many customers and potential customers along with price and delivery info. We compete and in some cases also partner with US aerospace companies that the US undoubtedly consider vital for it's national defense. I am pretty confident that if the TSA copied my phone or laptops's contents - while looking for terrorist plots or MP3s and handed it over to the NSA or whoever. Then if they found info that could be of commercial value to Boeing/Lockheed Martin/Raytheon etc then the NSA are not going to be prevented from passing those on by a sense politeness to a foreign visitor! That's why I get a clean wiped 'travel' laptop and a dumb phone to take, I use a VPN to check my email and I don't chat on a cell phone about how which US airlines are thinking of not buying Boeing.
