Blériot 5190

https://en.wikipedia.org/wiki/Bl%C3%A9riot_5190

The Blériot 5190 was a French transatlantic mail plane of the 1930s, a large
parasol-wing monoplane flying boat. It was of slightly unusual design, with a
low-profile hull and the crew compartment housed in the thick pylon that
supported the wing. The four engines were arranged with three along the leading
edge of the wing, and the fourth on the centreline of the trailing edge. It was
constructed for a French government contract to carry airmail to South America.

The first example, christened Santos-Dumont flew on 3 August 1933 and by the end
of 1934 had completed two proving flights across the South Atlantic, with Lucien
Bossoutrot at the commands and the future French Admiralty Chief of Staff Henri
Nomy as flight engineer. In February 1935 with Aéropostale's only other
transatlantic mailplane, the Latécoère 300 la Croix du Sud, out of commission
for maintenance, the Santos-Dumont entered service. From then until April, she
carried all of France's transatlantic mail at the rate of one crossing per week
until rejoined by la Croix du Sud and a new Farman F.220 named Le Centaure. As
part of this small fleet, the Santos-Dumont continued in this role until June
1937. Altogether, by that time, she had made 38 crossings of the Atlantic.

In the meantime, the French government had ordered a further three 5190s from
Blériot, and the company had borrowed heavily in order to build the aircraft.
Suddenly, the contract was cancelled without explanation or compensation,
forcing the firm into bankruptcy. Louis Blériot himself died of a heart attack
soon afterwards, on 1 August 1936.
