<p>I&#8217;m really enjoying the <a href="https://www.reddit.com/r/AdmiralCloudberg/">Admiral Cloudberg</a> series of aircraft accident investigation reports. How did I not know about these before??</p>
<p>A lot has improved in aviation safety since this crash in 1967, but there&#8217;s still a lot we can learn in SRE even now. For example: the operator&#8217;s view into the system should make the result of their inputs clear.</p>
