One of the problems with the early 727 was that the captains were mostly not experienced with swept-wing aircraft. You simply cannot fly, and especially land, a swept-wing jet like you do a straight-wing recip. For one thing if you get a big sinker going and you pull the nose up, in a swept wing, all you accomplish is to drive the mains into the ground harder. You can change the aircraft attitude but it is not going to do anything about the sink rate.
Personal hardest to fly was the Hiller OH

It had 200 HP
at sea level. I never had the privilege of flying it at sea level. It used control paddles on the main rotor head (check out the paddle angle at top center) which used aerodynamics instead of gyroscopic rigidity like you would get with the Bell helicopter stabilizer bars. So above about eight to ten thousand density altitude the control paddles were starting to approach stall angle. It got very sloppy and, frankly, scared me when it got like that. A tip of my hat to those who flew more powerful Hillers at higher elevations.
Happiness is not seeing another trite Ste. Maarten photo all week long.
