I actually saved him completely by accident. Somehow I totally missed the radio message that he needed help, but I must have crashed into the ground near there during one of my poorly timed manuevers, 'cause it got counted. I didn't notice anything 'til I got the end of mission narration and the narrator described landing and picking up the pilot. I was like, "Wait, I didn't do that!"
They actually show two pilots getting into the same fighter in the movie Battle of Britain. I think it was a Hurricane though and not a spit. (can't remember & I'm not at home, so I can't check.) It was during the RAF's evacuation of France. One of the pilots didn't have a working plane, so another pilot waved him over and they piled into the cockpit.
Also, if two pilots could wedge into a 109, they could definitely fit in a Spit, since I'm pretty sure the Spit had a bigger cockpit. I once saw a video of a German ace (can't remember which one, but it was one of the big names) sitting in the cockpit of a Spitfire. His first comment was, "Roomy!" In that same show a British ace got to check out the cockpit of the 109, and he didn't like it at all, mainly because of that rediculously fat frame around the canopy. Does anyone know why the 109 had that and why it wasn't replaced with a bubble canopy or something later in the war?
