The 3 engine Tri-Fokker was a popular early airliner.
Byrd flew one over the pole and hangered it where Henry Ford's engineers copied it and later reproduced it in aluminum as the 3 engined Tri-Ford
But the tri- Fokker's popularity abruptly ended when one went down because of a rotten wing spar.
Nobody wanted to fly in airplanes made of wood after that.
Ford's airliner became the one they wanted to travel in from then on.
