The cockpit crew must adjust speed and align perfectly with the runway for landing.

Just as planes are most vulnerable in the first three and last eight minutes, Natassa argues that human encounters follow a similar pattern. The first three minutes are when first impressions are formed, and the last eight minutes determine whether a meeting will lead to a new beginning or a final separation.

The pilot must stabilize the aircraft and control speed immediately after leaving the runway.
