Where is the evidence a plane can penetrate steel? If it was steel foil then yes, but massive 4" thick box columns?

Think kamikaze. Wooden planes through steel decks.
It was decided then that pilots would purposely crash their planes — with half a ton of explosives — into American warships.
Whaddya know?

There cases of unexploded bombs below decks. Learn your history.

Let's not exaggerate. Those "massive 4" thick box columns" were hollow, the walls averaging .37 inches in thickness.

Kamikaze aircraft were essentially pilot-guided explosive missiles, purpose-built or converted from conventional aircraft, without the ability to deliver torpedoes or bombs or attack other aircraft, or even to land. Pilots would attempt to crash their aircraft into enemy ships in what was called a "Body Attack" (体当たり; 体当り, taiatari) in planes laden with some combination of explosives, bombs, torpedoes and full fuel tanks; accuracy was much better than a conventional attack, and the payload larger.

The box columns had at least 4" thick walls at the impact points, four of them arranged in a box configuration. (they were 6" nearer the bottom, as they tapered in size, and had an extra steel plate in the center of the box)
That means the plane went through two 4" thick steel plates, and two 4" thick steel plates side on. There were 47 of those columns.

Core column at the bottom...
A little further up, they lose the middle plate and increase thickness from 5" to 6"...
And the top...
Where are you getting 0.37 from?
No exaggeration, just facts.

Regardless, at the their velocity, it seems the planes carried enough kinetic energy to easily sever the outer and some of the core columns.
Newton's laws of motion are three physical laws that form the basis for classical mechanics.
... in every interaction, there is a pair of forces acting on the two interacting objects. The size of the force on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.
Newton's third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum). According to Newton's third law, the forces on the two objects are equal in magnitude. While the forces are equal in magnitude and opposite in direction, the accelerations of the objects are not necessarily equal in magnitude. In accord with Newton's second law of motion, the acceleration of an object is dependent upon both force and mass. Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.
