Spring brings a blooming of aviation as entertainment. Whether a plane spotter goes to the airshow, or the airshow comes to the plane spotter, performances provide a fine opportunity to add a new aircraft genre to your spotting catalog. If the performer is flying a low-wing taildragger through a dazzling display of maneuvers, the aircraft could be one of Walter Extra’s aerobatic series. Two-seat Extra aircraft also serve as aerobatic trainers. Champion aerobatic pilot Patty Wagstaff’s Extra 260 is on display (inverted, naturally) in the Smithsonian National Air and Space Museum.
