Alex Davies Jul. 17, 2013, 2:49 PM There's a new United Airlines plane in the skies, with a dangerous-looking feature that will actually make it more efficient. The Boeing 737-800, which took its maiden test flight in Washington on Tuesday, is the first aircraft fitted with the new Split Scimitar Winglet, a curved attachment to the tip of the wing that is appropriately named for a sword. The winglets reduce wind drag, and can cut fuel use on the 737 by 2%. That doesn't sound like a ton, but United says that once the winglets are installed on its 737, 757, and 767 fleets, it will save more than $200 million per year. That's believable, considering that buying fuel accounted for 33% of global airline operating costs in 2012. United will begin retrofitting its 737-800 and 737-900ER jets with the winglets early next year, once it finishes testing and gets FAA certification.

Americans who have no experience with, or knowledge of, tyranny believe that only terrorists will experience the unchecked power of the state. They will believe this until it happens to them, or their children, or their friends.
