Is that a sliding windscreen/windshield on the Tri-Motor??? I hate to think what happens if it opens in flight!
Nicest view out of any passenger airplane was the old De Havilland Rapide. Lovely wicker tub chairs bolted to the floor.
(clickable photos - the last one is a 2.3Mb movie)
And check out the swivelling opening windows on the Rapide cockpit.
I was only young when we used this plane and my main memory is of an old lady who needed help to get up the slope of the plane on the ground - one of the ground crew put his shoulder to her backside and pushed her up to the front row!
