The Shoestring it is.
The Condor Shoestring (originally known as the Ast Special and the
Mercury Air Shoestring) was a Formula One racing aircraft built by Carl
and Vincent Ast to compete in the Cleveland National Air Races in 1949. It was a
highly streamlined mid-wing cantilever monoplane with fixed tailwheel
undercarriage. The mainwheels were covered with spats. The original aircraft
(registered N16V) was extensively rebuilt in 1965 and 1974, and by that
time had won fourteen first places, three second places and four third places.
