I don't understand your argument. This situation shows me that United doesn't understand security and that really scares me.
Google Glass is basically a dead devices when in airplane mode
(no data connection), so it's nothing more than a camera. Everyone else on the plane also has cameras on smartphones, tablets, laptops, and even pens and watches. In fact, last time I was in the airport I saw a "spy HD video camera pen" on sale at the Brookstone in the terminal.
United must be watching too much Mission Impossible
or Ocean's 11.
Do they really think people are infiltrating their planes after
getting through TSA Security by streaming video from Google Glass? And if that really is the case, why would the people not use an iPhone which is much less conspicuous?
