Agreed. Rodan survived falling on top of Anguirus, and then falling deep into the Earth's crust in Godzilla vs. Megalon, Godzilla has been dropped from great heights by kaiju such as Mecha King Ghidorah and Mothra, and Kaiju such as the Winged MUTO can easily swoop out of the way of the ground, provided that they are not travelling at terminal velocity.
