\When was the Scottish-born scientist, inventor and engineer died who formed "Silver Dart"?
AEA Silver Dart The Silver Dart (or Aerodrome #4) was a derivative of an early aircraft built by a Canadian/U.S. team, which after many successful flights in Hammondsport, New York, earlier in 1908, was dismantled and shipped to Baddeck, Nova Scotia. It was flown off the ice of Baddeck Bay, a sub-basin of Bras d'Or Lake, on 23 February 1909, making it the first controlled powered flight in Canada. The aircraft was piloted by one of its designers, John McCurdy. The original "Silver Dart" was designed and built by the Aerial Experiment Association (AEA), formed under the guidance of Dr. Alexander Graham Bell.
