This isn't exactly about FSX but here goes. Taking off in most planes is easy as well as keeping them in the air. The tricky part is landing them and it appears the first generation jet airliners were especially difficult to master. Not having the benefit of specific type training and not bothering to read things like best landing speed I have found so far that the Dehavilland Comet 4 is a bear. Slow down too much and it stalls out short of the runway. Keep the speed up and the brakes can't stop you before running off the end of the runway. And this was at LAX. I made a long shallow approach lined up 10 miles out and still couldn't touch down early enough to avoid running past the end of the pavement by about 100 ft.
The new jetliners are easy by comparison.
