The P-38 and the P-51 are my favorite aircraft of all times. I have a friend that flies a 51 for a museum and another friend that has a P-38 type rating on his license because he used to fly for a museum as well.
It was quite common for crews to hang up hammocks in the back of military transports and catch a nap on long hauls. Wonder if you could hang between the twin booms of the p-38?
I need to fire up my photoshop and see if I can make something up.
