* Planes are designed to fly: They're built to be light and aerodynamic, not to support heavy objects underneath.
* Landing gear: Planes have landing gear designed for landing and taking off, not for carrying extra weight.
* Safety: It would be extremely dangerous and likely impossible to securely attach a car to a plane.
However, there are some ways to relate cars and planes:
* Carriers: Large planes, like cargo planes, can transport cars inside their cargo holds.
* Underneath the plane: Cars can be transported *below* planes, but not directly underneath. This happens on car carriers, which are ships designed to transport vehicles.
* Symbolically: You can use the phrase "underneath the plane" to mean "in a situation of less power or importance" or "being overshadowed".
