F-104N Starfighter (4)
Dubbed the "missile with a man in it", the F-104 was essentially just that: a General Electric J79 engine with some wings and a pilot. If you could call them wings, that is. With a wingspan of only 21 feet, the Starfighter's wings were good for almost nothing except posing a hazard to ground crew--that is, they were 0.016 inches thick at the leading edge, which is essentially razor-thin. I spent quite some time narrowing down the fuselage aft of the intakes, eventually tapering down to four studs, the width of the fusleage.
