31. Struts joined the wheels, enclosed in fairings, to shock absorbers within the wing root aircraft fairings. 32. Wing loading could also be adjusted on the ground by attaching ballast to the wing roots . 33. The lower main-planes were attached to a framework, leaving a gap between wing root and fuselage. 34. Hard points for drop tanks were available at about of the way out from the wing root . 35. The wing root fairing is also glassfibre. 36. Like the earlier G models, all but the two wing root mounted MG 151 cannons were removed. 37. The tip airfoil stalls at a higher angle of attack, ensuring that the wing root stalls first. 38. The four engines would be buried in thickened wing roots ; the remaining wing planform was highly tapered. 39. The glider had a retractable landing gear and the wing roots provided lateral stability on the water. 40. Similarly, a decambered wing root glove was added to the Boeing 707 wing to create the Boeing 720.
