Replica in steel of the hydroplane "Santa Cruz"

The successful aerial cross took place in 1922, by the Portuguese Navy aeronauts Gago Coutinho and Sacadura Cabral, in a mono-engine hydroplane Fairey F-III - D MkII, specially designed for this purpose. Sacadura Cabral was the pilot and Gago Coutinho the navigator. The last one had adapted an artificial horizon to a sextant for measuring the altitude of the stars, revolutionary aerial invention by the time.
