The cockpit, whose sides are part of the engine compartment, are just held together by hopes and dreams.

And those struds (or however you spell it) below the wings "Don't push the rods in too far."

"Whoops, you've given them too much space, now the wings will push each other apart"

"Whoops, you wanted to correct it, now they are too far in and will rip the engine compartment apart"

"Oh, you want to correct that now? Too bad that they are practically glued together"
