The Piper PA-18 Super Cub is a two-seat, single-engine monoplane. Introduced in 1949 by Piper Aircraft, it was developed from the PA-11 Cub Special, and traces its lineage back through the J-3 Cub to the Taylor E-2 Cub of the 1930s. From Wikipedia
The small aircraft went down during an instructional flight over Crescent Lake, with recovery efforts ongoing.
