The rectus femoris becomes active in a leg extension because one of the actions of the rectus femoris is hip extension, as well as knee extension. The rectus femoris crosses both the hip and knee on the anterior side of the body. When the leg is extended it is one of the primary movers, whether it be straight leg extension, in which case it is the rectus femoris, illium and psoas muscles. In knee extension the rectus femoris works in conjunction with the other 3 quadriceps. However, in the case of a seated leg extension the rectus femois is less active, due to it already being shortened for the hip extension.
Hip adduction occurs in the frontal plane of motion. This movement involves bringing the leg toward the midline of the body.

Knee extension is primarily a sagittal plane movement that involves extension of the knee joint, resulting in straightening of the leg. It does not involve any specific type of rotation.
Leg extension exercises focus on quadriceps.
To effectively target your glutes with leg extension exercises, focus on squeezing your glutes at the top of the movement and using a full range of motion. Additionally, consider adding resistance bands or using a higher weight to increase the intensity of the exercise.
The hoist leg extension weight chart helps determine the right weight for leg extension exercises based on your strength level. It provides a range of weights to choose from to ensure a safe and effective workout.

You cannot pilot a plane with a broken leg, because you have to press the rudder peddals, but yes, you can fly on a plane with a broken leg.
