>Many readers familiar with the Comet disasters might be wondering why, with this article drawing to its close, I have yet to utter the phrase “square windows.” But the truth is that “square windows” never had anything to do with the Comet crashes. The windows were not and never were square — in fact, you can see for yourself in the above image, which shows a Comet 1 window next to a modern Boeing 737 window. Can you tell which is which? You probably can, but not because one is any more “square” than the other.[0]
