My grandfather was almost shot down at the White House (2018)
I've just finished reading, "Zero Fail: The Rise and Fall of the Secret Service" 
by Carol Leonnig [0]. In that book the author describes an incident on September 12, 1994 [1] in which a pilot landed a small plane in front of the white house. Secret Service members she interviewed were dumfounded that they were asked there to run to the white house roof with rifles to protect the building, and that there were no such thing as anti-aircraft missiles available at the time. More recently, another person landed a small aircraft on the Whitehouse grounds [2] with (apparently) no missiles involved.<p>Maybe the missiles are elsewhere, or maybe they're just a cost-effective rumor. The book makes it clear that the Secret Service is constantly underfunded and sorely lacking in modern technology, with agents sometimes having to use their personal car to transport the people they're protecting because their official cars aren't working.<p>[0] <a href="https://www.amazon.com/Zero-Fail-Rise-Secret-Service/dp/0399589015" rel="nofollow">https://www.amazon.com/Zero-Fail-Rise-Secret-Service/dp/0399...</a><p>[1] <a href="https://en.wikipedia.org/wiki/Frank_Eugene_Corder" rel="nofollow">https://en.wikipedia.org/wiki/Frank_Eugene_Corder</a><p>[2] <a href="https://www.cnn.com/2015/04/15/politics/aircraft-lands-on-capitol-grounds/index.html" rel="nofollow">https://www.cnn.com/2015/04/15/politics/aircraft-lands-on-ca...</a>
