because of possible jurisdictional jealousy between Harris (who flew with permission over Edwards Air Force Base} and those who oversee\u00a0nearby federal airspace. Harris had to fight the FAA for several years for not abiding by Federal Air Regulations.\u00a0 The story was one of\u00a0 literally high adventure followed by that sinking feeling one gets when having to contend with a government official seeking compliance with all rules at all times.<\/p>\n<p>A less contentious tale was shared by Scott Wiley, who told of long flights with Klaus Ohlmann in Argentina.\u00a0 Flying out of Calafate, Argentina, they managed a 14 hour, 23 minute flight that took them 1,612 kilometers (1,000 miles) at altitudes between 4,000 meters and 6,100 meters (12,800 to 19,520 feet).\u00a0\u00a0His videos were spectacular.<\/p>\n<p>ESA was originally the Homebuilt Sailplane Association, and two members kept the tradition alive.\u00a0 Les King asked, \u201cHow Far Will Watts Take Us?\u201d and proceeded to answer that with a look at available options for homebuilders who want an electric sailplane.\u00a0 His review of motors, controllers, and batteries showed the promise and limitations of current technology.\u00a0\u00a0 Murry Rozansky, also treasurer for the ESA, gave his ideas for a \u201cplank\u201d sailplane, showing the differences between straight wing and swept wing tailless airplanes, and previewing a standard-class or bigger sailplane with minimal tail surfaces and self-launching capabilities.\u00a0 He even alluded tothe possibilities for extruding wing panels, something he talked about at last year&#8217;s workshop.<\/p>\n<p>\u201cPure\u201d sailplanes need towplanes for launches, and John Ashford showed efforts to develop liquid-cooled automobile engines, including V-6 Fords and LZ-1 Corvette engines for such operations.\u00a0 Liquid cooling prevents the shock cooling that sometimes occurs in an air-cooled engine that first runs at full throttle dragging a glider into the air, then pretty immediately goes to full idle for a rapid descent back to the field.\u00a0 These American engines on Piper Pawnees give excellent performance and a better fuel burn than their aircraft engine equivalents.\u00a0 He ended with a Subaru-powered, high-wing craft with Polish Wilga-like gear for towing lighter craft.<\/p>\n<p>On the historical side, Jeff Byard, whose hangar houses the meetings every year, talked about early kit sailplanes, such as the Schweizer 1-26, and homebuilt sailplanes that could compete with professionally built craft until the advent of fiberglass craft.\u00a0 He noted the simplicity of instrumentation in earlier sailplanes and the increasing sophistication which has become the norm for competition today.<\/p>\n<p>On the historically literate side, Simine Short discussed her <a href=\"http:\/\/www.press.uillinois.edu\/books\/catalog\/56shm7qa9780252036316.html\">new book<\/a>, <em>Locomotive to Aeromotive: Octave Chanute and the Transportation Revolution<\/em>.\u00a0 Her presentation gave an overview of Chanute\u2019s engineering genius, including early railway innovations and wood preservation methods to make railway ties last longer.\u00a0 His enthusiasm for aircraft led him to design his own hang glider and to become a mentor to the Wright Brothers.\u00a0 Ms. Short noted that the hang glider design was stable enough to allow modern versions to be built and flown.\u00a0 From my reading so far, I can highly recommend this book, with its clear depiction of 19<sup>th<\/sup> century engineering techniques and early approaches to aeronautics.<\/p>\n<p>Jack Norris, mission director for the Voyager flight, talked about the theories that he\u00a0expands on\u00a0in his book, <a href=\"http:\/\/www.propellersexplained.com\/\">Propellers: The First and Final\u00a0Explanation<\/a>.\u00a0 He sold me a copy four years ago, and its extreme typography and design may look like a ransom note gone awry at first, but the ideas become clearer with every reading, and one gains some valuable insights into what makes a propeller work, and why we&#8217;ve been doing them wrong for many years.\u00a0 Several designers, following his precepts, have been achieving considerable gains in efficiency over &#8220;traditional&#8221; approaches.<\/p>\n<p>Greg Cole, head of <a href=\"http:\/\/windward-performance.com\/\">Windward Performance<\/a>, told of progress on Perlan 2, the airplane at the heart of the Perlan Project, destined to attempt a world altitude record of 90,000 feet in 2013, if current plans can be maintained.\u00a0 Greg is also working on the Goshawk, a Light Sport Aircraft motorglider powered by an HKS-700 two-cylinder engine and capable of Green Flight Challenge fuel economy.\u00a0 His Duckhawk, a 15-meter (49.2 feet) sailplane uses a Sparrowhawk fuselage and promises to be the highest performing standard-class sailplane in the world &#8211; if Greg has his way about it.\u00a0 Windward is producing the prototype of Joe Ben Bevirt&#8217;s Monarch, a vertical takeoff and landing commuter to be powered by eight Joby JM-1 motors.<\/p>\n<p>The Sunday session ended with a hum.\u00a0 Karl Klingbiel and Matt Keenon of <a href=\"http:\/\/www.avinc.com\/nano\">AeroVironment<\/a> showed off their highly sophisticated nano hummingbird drone, something that encapsulated the theories Phil Barnes and Al Bowers had discussed on Saturday in a small, highly maneuverable device (creature?).\u00a0 Following the designers\u2019 explication of what it took to gain simple hovering flight and to move as necessary to guide a sternum-mounted camera to its optimum viewing spot, the sight of the realistic-looking bird hovering over the audience and zooming from one person to another was a revelation not easily experienced in mere videos of the creation.\u00a0 The fact that such a \u201ccreature\u201d can video and audio record while in flight, or leave a \u201cbug\u201d to eavesdrop on a likely suspect makes it a potentially useful tool for national security, but also has the cloud of potential misuse that such inventions invariably seem to have hovering over them.<\/p>\n<p><iframe loading=\"lazy\" title=\"AeroVironment\/DARPA Nano Hummingbird UAV flying\" width=\"500\" height=\"281\"

families, but the early closure of the evening\u2019s potluck dinner and the cancellation of Gary Osaba\u2019s presentation on his many record flights.<\/p>\n<div id=\"attachment_4326\" style=\"width:
