The Metal Aircraft Corp. Flamingo was a monoplane produced in Cincinnati by the Metal Aircraft Corporation in the 1930s.[1]

Design and development[edit]

The Metal Aircraft Corporation purchased the design from the Halpin Development Co. and unveiled it at the 1929 National Air Races with Elinor Smith.[2][3] Following an accident at Bowman Field in May 1928, the prototype Flamingo was redesigned with a different nose, windscreen, and tail.[4]

Operational history[edit]

One G-2-W, named El Rio Caroní, is best remembered for its role in the discovery of Angel Falls by Jimmy Angel in 1935. Although well known to the local indigenous population, the falls had been glimpsed only by European explorers until Jimmy Angel crash-landed while attempting to land above the falls on Auyán-tepui during gold exploration.

The Metal Aircraft Corporation Flamingo that crashed above the falls was recovered by helicopter in the 1960s by the Venezuelan government and is on display at the entrance of the Ciudad Bolívar airport, in Venezuela. A replica was put in its place for visitors of the crash site.[5]

Other operators included the Mason & Dixon airline.[2]
