Barney's Mind
In the third part of the last episode, Barney goes back to Black Mesa's airport and flies Rosenberg and the other scientists back out in a passenger jet.
The fourth part goes further when he manages to outrun a fighter jet that tries to shoot them down, first by flying through a canyon to attempt dropping off the fighter's radar, then slowing down the plane so that the jet will be too fast to hit him... Only to stall from pitching up and idling the throttle but he then manages to recover out of the stall with only one engine after the left engine was set on fire and shut down due to damage. Barney even says "I'm awesome!" when he pulls it off. This whole thing bought him enough time when a portal storm teleported the jet fighter to Xen, allowing Barney and co. to escape.
