IMHO, every licensed pilot should be able to land in a 36kt crosswind irrespective of the crosswind componant (in this instance 20 degrees) , and maintain the runway centerline in the process given enough rudder and aileron input. That is a basic flying skill. A Professional in a 727 MUST make it look easy, that is what they get paid to do; even in the rain.
As for Jessica Cox, I respect all that she has accomplished given her physical limitations; however, the plane she is shown flying is one of the few that does not require the use of rudder to maintain "normal" roll, pitch and yaw flight charactoristics in all phases of flight. The design of the flight controls also make it possible for her to fly. A plane with a different yoke design or stick and a different throttle quadrant that has more levers and or vernier control would not allow her to make the required inputs I suspect.
And yes, WE L4P Marvericks are are hard to impress, as it should be. Double the wind speed, double the 20 degrees to 40 degrees and then make the wind gusty and then we can talk about being impressed. The afore mentioned is not atypical at many airports where GA pilots fly every day.
