I have seen a B-52 up close and personal. I'm not sure which aircraft (Harrier of B-52) has the greater anhedral . . . but the Harrier's is intentional, the B-52's is the result of its size.
The Swordfish was very effective. I dont think the slowest plane is a matter of opinion anyway There are several that were slower than the Swordfish (Fi-156 Storch, Piper Cub etc..)
The B-52s wings are straight (more or less) on the ground when the wing tanks, esp the drop tanks, are empty. The bogy wheels can sometimes be several feet off the ground. The transformation from an akward lump on the ground to an amazingly gracefull plane in the air is pretty incredible. Also the wings will flex over 30 feet when maneuvering in flight, they are very flexible.
