There's a rare bird indeed in this: at 10:25 there's a four-engined, shoulder-wing, monoplane. When I discovered that it couldn't be the A-W Ensign, I looked further and found it is the unique Fokker F.XXXVI. Wikipedia says there was only ever one because it couldn't compete with the Douglas designs, but compared with the DC-2 it had twice the number of Cyclones, but carried twice the number of pax.
