In the British Airways video that you see above, it shows off a trial being held on a flight from London to New York, where a passenger who is apparently enjoying a comedy on the inflight entertainment system is kept warm by a blue-to-purple blanket, while the other passenger right beside has a red blanket as a boxing match is shown.
British Airways has dubbed this the “Happiness Blanket”, but I do wonder whether it will catch on in due time. Too bad it cannot detect jealousy, otherwise the entire economy class might turn into a shade of green whenever someone from the first class cabin drops by with bling draped all over. I do wonder whether the Happiness Blanket might prove to be the undoing of a potential terrorist if he or she feels nervous before carrying out the intended attack.
