"Dave Hermance, Toyota&amp;#039;s Executive Engineer for Advanced Technology Vehicles in the U.S., died in a plane crash in California over the weekend, &amp;quot;doing the thing that he loved, aerobatics in his Russian Yak,&amp;quot; according to a Toyota news release.   Toyota&amp;#039;s statement went on to say: &amp;quot;Dave was our go-to guy for all hybrid and advanced vehicle info. We affectionately referred to him in-house as &amp;#039;The Professor.&amp;#039; He always had time to explain difficult technical stuff so that you and I could understand it.&amp;quot;   Hermance, 59, joined in 1991 as a senior manager, then became a general manager in the company&amp;#039;s powertrain department. Before that, he was with General Motors for a quarter-century, working on vehicle emissions and durability test development. "^^<http://www.w3.org/2001/XMLSchema#string>
