Boeing looked for flaws in its Dreamliner and couldn’t stop finding them
&gt; In 2019, they detected gaps between sections of the Dreamliner’s fuselage that were slightly wider than specified in the FAA-approved designs. The gaps, about the width of a piece of paper, were wider than the manufacturing tolerance of 0.005 of an inch allowed under the approved design.<p>I feel like the article is really grasping at straws here, and I&#x27;d be willing to bet the author doesn&#x27;t even comprehend how small this is. 0.005&quot; is <i>small</i>. For the hardware-challenged: 0.005&quot; is a typical manufacturing tolerance for a standard-spec PCB. Some of the Chinese board-houses that deal in high volume are higher than that[1]. The fact that they even found a gap this size on something the size of an airplane is amazing to me.<p>[1] <a href="https:&#x2F;&#x2F;www.pcbway.com&#x2F;pcb_prototype&#x2F;PCB_Manufacturing_tolerances.html" rel="nofollow">https:&#x2F;&#x2F;www.pcbway.com&#x2F;pcb_prototype&#x2F;PCB_Manufacturing_toler...</a>
