The US currently has 242 in private ownership (&amp;quot;N&amp;quot; tail number), involved in 14 fatal accidents since 1998. So a private L-39 would have had a &amp;gt;5% risk of killing its pilot to date, or about 0.4%&amp;#x2F;year.&lt;p&gt;&lt;a href=&quot;http://www.l39.com/content/incidents&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.l39.com&amp;#x2F;content&amp;#x2F;incidents&lt;/a&gt;&lt;p&gt;For comparison, the motorcycle fatality rate is about 0.1% per registered motorcycle per year,&lt;p&gt;&lt;a href=&quot;http://www.rita.dot.gov/bts/sites/rita.dot.gov.bts/files/publications/special_reports_and_issue_briefs/special_report/2009_05_14/html/entire.html&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.rita.dot.gov&amp;#x2F;bts&amp;#x2F;sites&amp;#x2F;rita.dot.gov.bts&amp;#x2F;files&amp;#x2F;pub...&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>Ken Thompson flies a MiG-29 (1999)</title><url>http://cm.bell-labs.com/cm/cs/who/ken/mig.html</url></story>

  maneuver. He flew level and pulled up so fast that the
  plane stalled. The plane continued to move horizontally 
  in a flat stall while pointing up. At some point Vladimir 
  performed some magic and the plane leaned over horizontal
  and flew normally. The result was a loss of 300 kmph in
  seconds. This was described to me as a courtesy maneuver
  to allow tailgating traffic to pass.
&lt;/code&gt;&lt;/pre&gt;
Which year was this? I thought &amp;#x27;cobra&amp;#x27; was a post Sukhoi-27 thing. I didnt even know a MiG-29 could do that. Can all of them do it, or some later versions ?&lt;p&gt;@quickpost Thanks you answered my question.</text><parent_chain></parent_chain></comment><story><title>Ken Thompson flies a MiG-29 (1999)</title><url>http://cm.bell-labs.com/cm/cs/who/ken/mig.html</url></story>
