Just to underline this point, here&#x27;s a very modern (incident in May, 2014, reporting apparently Jan 23, 2016) nuclear weapon mishap that was hidden: <a href="http:&#x2F;&#x2F;talkingpointsmemo.com&#x2F;news&#x2F;air-force-nuclear-missile-damage" rel="nofollow">http:&#x2F;&#x2F;talkingpointsmemo.com&#x2F;news&#x2F;air-force-nuclear-missile-...</a><p>I will grant you that the Air Force tried double-speak and obfuscation to hide the incident rather than over-classification, but they did refuse a FOIA request about it and hid the incident from a Secretary of Defense appointed commission.
