When news broke about U.S. government agencies collecting metadata about its citizens’ Internet and phone communications, many were surprised by its scope. The surveillance covered a vast number of Internet messages and phone calls.

There’s been a lot of talk recently about PRISM, which may allow the US National Security Agency - and anyone they choose - to access some of our personal online information if it passes through the USA.

And, in a reverse of the normal pattern of technology innovation, a development driven by consumers is set to have an important impact on aerospace and defence (A&D).
