Yes, the cockpit has an “escape rope”. It’s not always an actual rope (more like a strap) & not all jets have one (but most do). It’s rolled up & stored in a small compartment above the window, anchored to the frame. In an emergency, you open the side window, toss the rope & use it to climb out. Not sure all pilots could do this these days…some of us are carrying a few extra pounds 😉. The window can be opened in flight, if needed, to ventilate excess smoke in a fire scenario which would block your view. There’s a speed limit…somewhere around 200 knots. You’d have to depressurize first, though.
