The Seeleys and SA board members did themselves proud for this year’s Sustainable Aviation Symposium.  Your editor visited the grand ballroom in the San Francisco Bay Pullman Hotel the night before the meeting was to take place.  All the tables, chairs and stage were in place, but the room was otherwise bare.  Early next morning, your editor trudged downstairs again, to be met with an astonishing sight.  At the back of the ballroom, a pair of exotic geometric shapes glowed in blue and green lighting.  Somehow, a 50-foot wing and substantial streamlined shape had materialized overnight.  Already, attendees were peering up at the extremely twisted tips of the wings and trying to analyze what they saw before them.
