100 Words On: The Department of Redundancy Department

When it comes to the world of banking, nobody seems to have any problem with redundancy. How else can you explain the fact that people routinely use their PIN number at the ATM machine? If you ask a linguist, he’ll boldly proclaim that redundancy should be avoided at all costs. But that’s not always true. Engineers demand a belt-and-suspenders approach when designing safety into passenger airplanes; it’s the primary reason why flying is the safest form of travel, including walking.

The bottom line: Redundant redundancy is redundant, but that’s not always a bad thing — especially when you’re flying at 37,000 feet.
