"These touch screens selectively display the necessary controls during flight and are the primary interface astronauts have with the vehicle. Below are two rows of manual buttons, 38 in total, that provide back-up control of the spacecraft. Many of the buttons are situated beneath clear panels, intended to never be used, because they are often the third option after the touch screens and ground control of the Dragon[…]
One control stood out—a large black and red handle in the middle of the console with “EJECT” printed in clear white letters above it. This initiates the launch escape system, which rapidly pulls the spacecraft away from the rocket in the case of an emergency during the ascent into space. It must be pulled, then twisted. Normally the flight computers would initiate such a maneuver, but the prominence of the escape system handle underlines its importance. Notably, after the vehicle reaches orbit, this control becomes “deadened,” such that accidentally pulling it in space would do nothing."
