Page "Ladder paradox" Paragraph 5

Conversely, through symmetry, from the reference frame of the ladder it is the garage that is moving with a relative velocity and so it is the garage that undergoes a length contraction.

From this perspective, the garage is made even smaller and it is impossible to fit the ladder into the garage. Figure 3: In the ladder frame, the garage undergoes length contraction and seems too small to contain the ladder.
